 \chapter{Introduction}
 \LaTeX{} is a document preparation system for 
 the \TeX{} typesetting program. It offers excellent
 programmable desktop publishing features and 
 extensive facilities for automating most 
 aspects of typesetting and desktop publishing, 
 including numbering and  cross-referencing, 
 tables and figures, page layout, 
 bibliographies, and much more. \LaTeX{} was 
 originally written in 1984 by Leslie Lamport 
 and has become the dominant method for using 
 \TeX; few people write in plain \TeX{} anymore. 
 The current version is \LaTeXe.

       Version 1.3, 3 November 2008
 \end{center}
 Copyright \copyright{} 2000, 2001, 2002, 2007, 2008  Free Software Foundation, Inc.
 \href{http://fsf.org/}{<http://fsf.org/>}
 Everyone is permitted to copy and distribute verbatim copies
 of this license document, but changing it is not allowed.
 {\large\bf 0. PREAMBLE \par}
 The purpose of this License is to make a manual, textbook, or other
 functional and useful document ``free'' in the sense of freedom: to
 assure everyone the effective freedom to copy and redistribute it,
 with or without modifying it, either commercially or noncommercially.
 Secondarily, this License preserves for the author and publisher a way
 to get credit for their work, while not being considered responsible
 for modifications made by others.
 This License is a kind of ``copyleft'', which means that derivative
 works of the document must themselves be free in the same sense.  It
 complements the GNU General Public License, which is a copyleft
 license designed for free software.
 We have designed this License in order to use it for manuals for free
 software, because free software needs free documentation: a free
 program should come with manuals providing the same freedoms that the
 software does.  But this License is not limited to software manuals;
 it can be used for any textual work, regardless of subject matter or
 whether it is published as a printed book.  We recommend this License
 principally for works whose purpose is instruction or reference.
 {\large\bf 1. APPLICABILITY AND DEFINITIONS\par}
 %\phantomsection
 %\addcontentsline{toc}{section}{1. APPLICABILITY AND DEFINITIONS}
 This License applies to any manual or other work, in any medium, that
 contains a notice placed by the copyright holder saying it can be
 distributed under the terms of this License.  Such a notice grants a
 world-wide, royalty-free license, unlimited in duration, to use that
 work under the conditions stated herein.  The ``\textbf{Document}'', below,
 refers to any such manual or work.  Any member of the public is a
 licensee, and is addressed as ``\textbf{you}''.  You accept the license if you
 copy, modify or distribute the work in a way requiring permission
 under copyright law.
 A ``\textbf{Modified Version}'' of the Document means any work containing the
 Document or a portion of it, either copied verbatim, or with
 modifications and/or translated into another language.
 A ``\textbf{Secondary Section}'' is a named appendix or a front-matter section of
 the Document that deals exclusively with the relationship of the
 publishers or authors of the Document to the Document's overall subject
 (or to related matters) and contains nothing that could fall directly
 within that overall subject.  (Thus, if the Document is in part a
 textbook of mathematics, a Secondary Section may not explain any
 mathematics.)  The relationship could be a matter of historical
 connection with the subject or with related matters, or of legal,
 commercial, philosophical, ethical or political position regarding
 them.
 The ``\textbf{Invariant Sections}'' are certain Secondary Sections whose titles
 are designated, as being those of Invariant Sections, in the notice
 that says that the Document is released under this License.  If a
 section does not fit the above definition of Secondary then it is not
 allowed to be designated as Invariant.  The Document may contain zero
 Invariant Sections.  If the Document does not identify any Invariant
 Sections then there are none.
 The ``\textbf{Cover Texts}'' are certain short passages of text that are listed,
 as Front-Cover Texts or Back-Cover Texts, in the notice that says that
 the Document is released under this License.  A Front-Cover Text may
 be at most 5 words, and a Back-Cover Text may be at most 25 words.
 A ``\textbf{Transparent}'' copy of the Document means a machine-readable copy,
 represented in a format whose specification is available to the
 general public, that is suitable for revising the document
 straightforwardly with generic text editors or (for images composed of
 pixels) generic paint programs or (for drawings) some widely available
 drawing editor, and that is suitable for input to text formatters or
 for automatic translation to a variety of formats suitable for input
 to text formatters.  A copy made in an otherwise Transparent file
 format whose markup, or absence of markup, has been arranged to thwart
 or discourage subsequent modification by readers is not Transparent.
 An image format is not Transparent if used for any substantial amount
 of text.  A copy that is not ``Transparent'' is called ``\textbf{Opaque}''.
 Examples of suitable formats for Transparent copies include plain
 ASCII without markup, Texinfo input format, LaTeX input format, SGML
 or XML using a publicly available DTD, and standard-conforming simple
 HTML, PostScript or PDF designed for human modification.  Examples of
 transparent image formats include PNG, XCF and JPG.  Opaque formats
 include proprietary formats that can be read and edited only by
 proprietary word processors, SGML or XML for which the DTD and/or
 processing tools are not generally available, and the
 machine-generated HTML, PostScript or PDF produced by some word
 processors for output purposes only.
 The ``\textbf{Title Page}'' means, for a printed book, the title page itself,
 plus such following pages as are needed to hold, legibly, the material
 this License requires to appear in the title page.  For works in
 formats which do not have any title page as such, ``Title Page'' means
 the text near the most prominent appearance of the work's title,
 preceding the beginning of the body of the text.
 The ``\textbf{publisher}'' means any person or entity that distributes
 copies of the Document to the public.
 A section ``\textbf{Entitled XYZ}'' means a named subunit of the Document whose
 title either is precisely XYZ or contains XYZ in parentheses following
 text that translates XYZ in another language.  (Here XYZ stands for a
 specific section name mentioned below, such as ``\textbf{Acknowledgements}'',
 ``\textbf{Dedications}'', ``\textbf{Endorsements}'', or ``\textbf{History}''.)  
 To ``\textbf{Preserve the Title}''
 of such a section when you modify the Document means that it remains a
 section ``Entitled XYZ'' according to this definition.
 The Document may include Warranty Disclaimers next to the notice which
 states that this License applies to the Document.  These Warranty
 Disclaimers are considered to be included by reference in this
 License, but only as regards disclaiming warranties: any other
 implication that these Warranty Disclaimers may have is void and has
 no effect on the meaning of this License.
 {\large\bf 2. VERBATIM COPYING\par}
 %\phantomsection
 %\addcontentsline{toc}{section}{2. VERBATIM COPYING}
 You may copy and distribute the Document in any medium, either
 commercially or noncommercially, provided that this License, the
 copyright notices, and the license notice saying this License applies
 to the Document are reproduced in all copies, and that you add no other
 conditions whatsoever to those of this License.  You may not use
 technical measures to obstruct or control the reading or further
 copying of the copies you make or distribute.  However, you may accept
 compensation in exchange for copies.  If you distribute a large enough
 number of copies you must also follow the conditions in section~3.
 You may also lend copies, under the same conditions stated above, and
 you may publicly display copies.
 {\large\bf 3. COPYING IN QUANTITY\par}
 %\phantomsection
 %\addcontentsline{toc}{section}{3. COPYING IN QUANTITY}
 If you publish printed copies (or copies in media that commonly have
 printed covers) of the Document, numbering more than 100, and the
 Document's license notice requires Cover Texts, you must enclose the
 copies in covers that carry, clearly and legibly, all these Cover
 Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on
 the back cover.  Both covers must also clearly and legibly identify
 you as the publisher of these copies.  The front cover must present
 the full title with all words of the title equally prominent and
 visible.  You may add other material on the covers in addition.
 Copying with changes limited to the covers, as long as they preserve
 the title of the Document and satisfy these conditions, can be treated
 as verbatim copying in other respects.
 If the required texts for either cover are too voluminous to fit
 legibly, you should put the first ones listed (as many as fit
 reasonably) on the actual cover, and continue the rest onto adjacent
 pages.
 If you publish or distribute Opaque copies of the Document numbering
 more than 100, you must either include a machine-readable Transparent
 copy along with each Opaque copy, or state in or with each Opaque copy
 a computer-network location from which the general network-using
 public has access to download using public-standard network protocols
 a complete Transparent copy of the Document, free of added material.
 If you use the latter option, you must take reasonably prudent steps,
 when you begin distribution of Opaque copies in quantity, to ensure
 that this Transparent copy will remain thus accessible at the stated
 location until at least one year after the last time you distribute an
 Opaque copy (directly or through your agents or retailers) of that
 edition to the public.
 It is requested, but not required, that you contact the authors of the
 Document well before redistributing any large number of copies, to give
 them a chance to provide you with an updated version of the Document.
 {\large\bf 4. MODIFICATIONS\par}
 %\phantomsection
 %\addcontentsline{toc}{section}{4. MODIFICATIONS}
 You may copy and distribute a Modified Version of the Document under
 the conditions of sections 2 and 3 above, provided that you release
 the Modified Version under precisely this License, with the Modified
 Version filling the role of the Document, thus licensing distribution
 and modification of the Modified Version to whoever possesses a copy
 of it.  In addition, you must do these things in the Modified Version:
 \begin{itemize}
 \item[A.] 
   Use in the Title Page (and on the covers, if any) a title distinct
   from that of the Document, and from those of previous versions
   (which should, if there were any, be listed in the History section
   of the Document).  You may use the same title as a previous version
   if the original publisher of that version gives permission.
 \item[B.]
   List on the Title Page, as authors, one or more persons or entities
   responsible for authorship of the modifications in the Modified
   Version, together with at least five of the principal authors of the
   Document (all of its principal authors, if it has fewer than five),
   unless they release you from this requirement.
 \item[C.]
   State on the Title page the name of the publisher of the
   Modified Version, as the publisher.
 \item[D.]
   Preserve all the copyright notices of the Document.
 \item[E.]
   Add an appropriate copyright notice for your modifications
   adjacent to the other copyright notices.
 \item[F.]
   Include, immediately after the copyright notices, a license notice
   giving the public permission to use the Modified Version under the
   terms of this License, in the form shown in the Addendum below.
 \item[G.]
   Preserve in that license notice the full lists of Invariant Sections
   and required Cover Texts given in the Document's license notice.
 \item[H.]
   Include an unaltered copy of this License.
 \item[I.]
   Preserve the section Entitled ``History'', Preserve its Title, and add
   to it an item stating at least the title, year, new authors, and
   publisher of the Modified Version as given on the Title Page.  If
   there is no section Entitled ``History'' in the Document, create one
   stating the title, year, authors, and publisher of the Document as
   given on its Title Page, then add an item describing the Modified
   Version as stated in the previous sentence.
 \item[J.]
   Preserve the network location, if any, given in the Document for
   public access to a Transparent copy of the Document, and likewise
   the network locations given in the Document for previous versions
   it was based on.  These may be placed in the ``History'' section.
   You may omit a network location for a work that was published at
   least four years before the Document itself, or if the original
   publisher of the version it refers to gives permission.
 \item[K.]
   For any section Entitled ``Acknowledgements'' or ``Dedications'',
   Preserve the Title of the section, and preserve in the section all
   the substance and tone of each of the contributor acknowledgements
   and/or dedications given therein.
 \item[L.]
   Preserve all the Invariant Sections of the Document,
   unaltered in their text and in their titles.  Section numbers
   or the equivalent are not considered part of the section titles.
 \item[M.]
   Delete any section Entitled ``Endorsements''.  Such a section
   may not be included in the Modified Version.
 \item[N.]
   Do not retitle any existing section to be Entitled ``Endorsements''
   or to conflict in title with any Invariant Section.
 \item[O.]
   Preserve any Warranty Disclaimers.
 \end{itemize}
 If the Modified Version includes new front-matter sections or
 appendices that qualify as Secondary Sections and contain no material
 copied from the Document, you may at your option designate some or all
 of these sections as invariant.  To do this, add their titles to the
 list of Invariant Sections in the Modified Version's license notice.
 These titles must be distinct from any other section titles.
 You may add a section Entitled ``Endorsements'', provided it contains
 nothing but endorsements of your Modified Version by various
 parties---for example, statements of peer review or that the text has
 been approved by an organization as the authoritative definition of a
 standard.
 You may add a passage of up to five words as a Front-Cover Text, and a
 passage of up to 25 words as a Back-Cover Text, to the end of the list
 of Cover Texts in the Modified Version.  Only one passage of
 Front-Cover Text and one of Back-Cover Text may be added by (or
 through arrangements made by) any one entity.  If the Document already
 includes a cover text for the same cover, previously added by you or
 by arrangement made by the same entity you are acting on behalf of,
 you may not add another; but you may replace the old one, on explicit
 permission from the previous publisher that added the old one.
 The author(s) and publisher(s) of the Document do not by this License
 give permission to use their names for publicity for or to assert or
 imply endorsement of any Modified Version.
 {\large\bf 5. COMBINING DOCUMENTS\par}
 %\phantomsection
 %\addcontentsline{toc}{section}{5. COMBINING DOCUMENTS}
 You may combine the Document with other documents released under this
 License, under the terms defined in section~4 above for modified
 versions, provided that you include in the combination all of the
 Invariant Sections of all of the original documents, unmodified, and
 list them all as Invariant Sections of your combined work in its
 license notice, and that you preserve all their Warranty Disclaimers.
 The combined work need only contain one copy of this License, and
 multiple identical Invariant Sections may be replaced with a single
 copy.  If there are multiple Invariant Sections with the same name but
 different contents, make the title of each such section unique by
 adding at the end of it, in parentheses, the name of the original
 author or publisher of that section if known, or else a unique number.
 Make the same adjustment to the section titles in the list of
 Invariant Sections in the license notice of the combined work.
 In the combination, you must combine any sections Entitled ``History''
 in the various original documents, forming one section Entitled
 ``History''; likewise combine any sections Entitled ``Acknowledgements'',
 and any sections Entitled ``Dedications''.  You must delete all sections
 Entitled ``Endorsements''.
 {\large\bf 6. COLLECTIONS OF DOCUMENTS\par}
 %\phantomsection
 %\addcontentsline{toc}{section}{6. COLLECTIONS OF DOCUMENTS}
 You may make a collection consisting of the Document and other documents
 released under this License, and replace the individual copies of this
 License in the various documents with a single copy that is included in
 the collection, provided that you follow the rules of this License for
 verbatim copying of each of the documents in all other respects.
 You may extract a single document from such a collection, and distribute
 it individually under this License, provided you insert a copy of this
 License into the extracted document, and follow this License in all
 other respects regarding verbatim copying of that document.
 {\large\bf 7. AGGREGATION WITH INDEPENDENT WORKS\par}
 %\phantomsection
 %\addcontentsline{toc}{section}{7. AGGREGATION WITH INDEPENDENT WORKS}
 A compilation of the Document or its derivatives with other separate
 and independent documents or works, in or on a volume of a storage or
 distribution medium, is called an ``aggregate'' if the copyright
 resulting from the compilation is not used to limit the legal rights
 of the compilation's users beyond what the individual works permit.
 When the Document is included in an aggregate, this License does not
 apply to the other works in the aggregate which are not themselves
 derivative works of the Document.
 If the Cover Text requirement of section~3 is applicable to these
 copies of the Document, then if the Document is less than one half of
 the entire aggregate, the Document's Cover Texts may be placed on
 covers that bracket the Document within the aggregate, or the
 electronic equivalent of covers if the Document is in electronic form.
 Otherwise they must appear on printed covers that bracket the whole
 aggregate.
 {\large\bf 8. TRANSLATION\par}
 %\phantomsection
 %\addcontentsline{toc}{section}{8. TRANSLATION}
 Translation is considered a kind of modification, so you may
 distribute translations of the Document under the terms of section~4.
 Replacing Invariant Sections with translations requires special
 permission from their copyright holders, but you may include
 translations of some or all Invariant Sections in addition to the
 original versions of these Invariant Sections.  You may include a
 translation of this License, and all the license notices in the
 Document, and any Warranty Disclaimers, provided that you also include
 the original English version of this License and the original versions
 of those notices and disclaimers.  In case of a disagreement between
 the translation and the original version of this License or a notice
 or disclaimer, the original version will prevail.
 If a section in the Document is Entitled ``Acknowledgements'',
 ``Dedications'', or ``History'', the requirement (section~4) to Preserve
 its Title (section~1) will typically require changing the actual
 title.
 {\large\bf 9. TERMINATION\par}
 %\phantomsection
 %\addcontentsline{toc}{section}{9. TERMINATION}
 You may not copy, modify, sublicense, or distribute the Document
 except as expressly provided under this License.  Any attempt
 otherwise to copy, modify, sublicense, or distribute it is void, and
 will automatically terminate your rights under this License.
 However, if you cease all violation of this License, then your license
 from a particular copyright holder is reinstated (a) provisionally,
 unless and until the copyright holder explicitly and finally
 terminates your license, and (b) permanently, if the copyright holder
 fails to notify you of the violation by some reasonable means prior to
 60 days after the cessation.
 Moreover, your license from a particular copyright holder is
 reinstated permanently if the copyright holder notifies you of the
 violation by some reasonable means, this is the first time you have
 received notice of violation of this License (for any work) from that
 copyright holder, and you cure the violation prior to 30 days after
 your receipt of the notice.
 Termination of your rights under this section does not terminate the
 licenses of parties who have received copies or rights from you under
 this License.  If your rights have been terminated and not permanently
 reinstated, receipt of a copy of some or all of the same material does
 not give you any rights to use it.
 {\large\bf 10. FUTURE REVISIONS OF THIS LICENSE\par}
 %\phantomsection
 %\addcontentsline{toc}{section}{10. FUTURE REVISIONS OF THIS LICENSE}
 The Free Software Foundation may publish new, revised versions
 of the GNU Free Documentation License from time to time.  Such new
 versions will be similar in spirit to the present version, but may
 differ in detail to address new problems or concerns.  See
 \texttt{http://www.gnu.org/copyleft/}.
 Each version of the License is given a distinguishing version number.
 If the Document specifies that a particular numbered version of this
 License ``or any later version'' applies to it, you have the option of
 following the terms and conditions either of that specified version or
 of any later version that has been published (not as a draft) by the
 Free Software Foundation.  If the Document does not specify a version
 number of this License, you may choose any version ever published (not
 as a draft) by the Free Software Foundation.  If the Document
 specifies that a proxy can decide which future versions of this
 License can be used, that proxy's public statement of acceptance of a
 version permanently authorizes you to choose that version for the
 Document.
 {\large\bf 11. RELICENSING\par}
 %\phantomsection
 %\addcontentsline{toc}{section}{11. RELICENSING}
 ``Massive Multiauthor Collaboration Site'' (or ``MMC Site'') means any
 World Wide Web server that publishes copyrightable works and also
 provides prominent facilities for anybody to edit those works.  A
 public wiki that anybody can edit is an example of such a server.  A
 ``Massive Multiauthor Collaboration'' (or ``MMC'') contained in the
 site means any set of copyrightable works thus published on the MMC
 site.
 ``CC-BY-SA'' means the Creative Commons Attribution-Share Alike 3.0
 license published by Creative Commons Corporation, a not-for-profit
 corporation with a principal place of business in San Francisco,
 California, as well as future copyleft versions of that license
 published by that same organization.
 ``Incorporate'' means to publish or republish a Document, in whole or
 in part, as part of another Document.
 An MMC is ``eligible for relicensing'' if it is licensed under this
 License, and if all works that were first published under this License
 somewhere other than this MMC, and subsequently incorporated in whole
 or in part into the MMC, (1) had no cover texts or invariant sections,
 and (2) were thus incorporated prior to November 1, 2008.
 The operator of an MMC Site may republish an MMC contained in the site
 under CC-BY-SA on the same site at any time before August 1, 2009,
 provided the MMC is eligible for relicensing.
 {\large\bf ADDENDUM: How to use this License for your documents\par}
 %\phantomsection
 %\addcontentsline{toc}{section}{ADDENDUM: How to use this License for your documents}
 To use this License in a document you have written, include a copy of
 the License in the document and put the following copyright and
 license notices just after the title page:
 \bigskip
 \begin{quote}
    Copyright \copyright{}  YEAR  YOUR NAME.
    Permission is granted to copy, distribute and/or modify this document
    under the terms of the GNU Free Documentation License, Version 1.3
    or any later version published by the Free Software Foundation;
    with no Invariant Sections, no Front-Cover Texts, and no Back-Cover Texts.
    A copy of the license is included in the section entitled ``GNU
    Free Documentation License''.
 \end{quote}
 \bigskip
 If you have Invariant Sections, Front-Cover Texts and Back-Cover Texts,
 replace the ``with \dots\ Texts.''\ line with this:
 \bigskip
 \begin{quote}
    with the Invariant Sections being LIST THEIR TITLES, with the
    Front-Cover Texts being LIST, and with the Back-Cover Texts being LIST.
 \end{quote}
 \bigskip
 If you have Invariant Sections without Cover Texts, or some other
 combination of the three, merge those two alternatives to suit the
 situation.
 If your document contains nontrivial examples of program code, we
 recommend releasing these examples in parallel under your choice of
 free software license, such as the GNU General Public License,
 to permit their use in free software.

 \href{http://fsf.org/}{<http://fsf.org/>}
 Everyone is permitted to copy and distribute verbatim copies
 of this license document, but changing it is not allowed.
 \textbf{0. PREAMBLE}
 The purpose of this License is to make a manual, textbook, or other
 functional and useful document ``free'' in the sense of freedom: to
 assure everyone the effective freedom to copy and redistribute it,
 with or without modifying it, either commercially or noncommercially.
 Secondarily, this License preserves for the author and publisher a way
 to get credit for their work, while not being considered responsible
 for modifications made by others.
 This License is a kind of ``copyleft'', which means that derivative
 works of the document must themselves be free in the same sense.  It
 complements the GNU General Public License, which is a copyleft
 license designed for free software.
 We have designed this License in order to use it for manuals for free
 software, because free software needs free documentation: a free
 program should come with manuals providing the same freedoms that the
 software does.  But this License is not limited to software manuals;
 it can be used for any textual work, regardless of subject matter or
 whether it is published as a printed book.  We recommend this License
 principally for works whose purpose is instruction or reference.
 \textbf{1. APPLICABILITY AND DEFINITIONS}
 This License applies to any manual or other work, in any medium, that
 contains a notice placed by the copyright holder saying it can be
 distributed under the terms of this License.  Such a notice grants a
 world-wide, royalty-free license, unlimited in duration, to use that
 work under the conditions stated herein.  The ``Document'', below,
 refers to any such manual or work.  Any member of the public is a
 licensee, and is addressed as ``you''.  You accept the license if you
 copy, modify or distribute the work in a way requiring permission
 under copyright law.
 A ``Modified Version'' of the Document means any work containing the
 Document or a portion of it, either copied verbatim, or with
 modifications and/or translated into another language.
 A ``Secondary Section'' is a named appendix or a front-matter section of
 the Document that deals exclusively with the relationship of the
 publishers or authors of the Document to the Document's overall subject
 (or to related matters) and contains nothing that could fall directly
 within that overall subject.  (Thus, if the Document is in part a
 textbook of mathematics, a Secondary Section may not explain any
 mathematics.)  The relationship could be a matter of historical
 connection with the subject or with related matters, or of legal,
 commercial, philosophical, ethical or political position regarding
 them.
 The ``Invariant Sections'' are certain Secondary Sections whose titles
 are designated, as being those of Invariant Sections, in the notice
 that says that the Document is released under this License.  If a
 section does not fit the above definition of Secondary then it is not
 allowed to be designated as Invariant.  The Document may contain zero
 Invariant Sections.  If the Document does not identify any Invariant
 Sections then there are none.
 The ``Cover Texts'' are certain short passages of text that are listed,
 as Front-Cover Texts or Back-Cover Texts, in the notice that says that
 the Document is released under this License.  A Front-Cover Text may
 be at most 5 words, and a Back-Cover Text may be at most 25 words.
 A ``Transparent'' copy of the Document means a machine-readable copy,
 represented in a format whose specification is available to the
 general public, that is suitable for revising the document
 straightforwardly with generic text editors or (for images composed of
 pixels) generic paint programs or (for drawings) some widely available
 drawing editor, and that is suitable for input to text formatters or
 for automatic translation to a variety of formats suitable for input
 to text formatters.  A copy made in an otherwise Transparent file
 format whose markup, or absence of markup, has been arranged to thwart
 or discourage subsequent modification by readers is not Transparent.
 An image format is not Transparent if used for any substantial amount
 of text.  A copy that is not ``Transparent'' is called ``Opaque''.
 Examples of suitable formats for Transparent copies include plain
 ASCII without markup, Texinfo input format, LaTeX input format, SGML
 or XML using a publicly available DTD, and standard-conforming simple
 HTML, PostScript or PDF designed for human modification.  Examples of
 transparent image formats include PNG, XCF and JPG.  Opaque formats
 include proprietary formats that can be read and edited only by
 proprietary word processors, SGML or XML for which the DTD and/or
 processing tools are not generally available, and the
 machine-generated HTML, PostScript or PDF produced by some word
 processors for output purposes only.
 The ``Title Page'' means, for a printed book, the title page itself,
 plus such following pages as are needed to hold, legibly, the material
 this License requires to appear in the title page.  For works in
 formats which do not have any title page as such, ``Title Page'' means
 the text near the most prominent appearance of the work's title,
 preceding the beginning of the body of the text.
 The ``publisher'' means any person or entity that distributes
 copies of the Document to the public.
 A section ``Entitled XYZ'' means a named subunit of the Document whose
 title either is precisely XYZ or contains XYZ in parentheses following
 text that translates XYZ in another language.  (Here XYZ stands for a
 specific section name mentioned below, such as ``Acknowledgements'',
 ``Dedications'', ``Endorsements'', or ``History''.)  
 To ``Preserve the Title''
 of such a section when you modify the Document means that it remains a
 section ``Entitled XYZ'' according to this definition.
 The Document may include Warranty Disclaimers next to the notice which
 states that this License applies to the Document.  These Warranty
 Disclaimers are considered to be included by reference in this
 License, but only as regards disclaiming warranties: any other
 implication that these Warranty Disclaimers may have is void and has
 no effect on the meaning of this License.
 \textbf{2. VERBATIM COPYING}
 You may copy and distribute the Document in any medium, either
 commercially or noncommercially, provided that this License, the
 copyright notices, and the license notice saying this License applies
 to the Document are reproduced in all copies, and that you add no other
 conditions whatsoever to those of this License.  You may not use
 technical measures to obstruct or control the reading or further
 copying of the copies you make or distribute.  However, you may accept
 compensation in exchange for copies.  If you distribute a large enough
 number of copies you must also follow the conditions in section~3.
 You may also lend copies, under the same conditions stated above, and
 you may publicly display copies.
 \textbf{3. COPYING IN QUANTITY}
 If you publish printed copies (or copies in media that commonly have
 printed covers) of the Document, numbering more than 100, and the
 Document's license notice requires Cover Texts, you must enclose the
 copies in covers that carry, clearly and legibly, all these Cover
 Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on
 the back cover.  Both covers must also clearly and legibly identify
 you as the publisher of these copies.  The front cover must present
 the full title with all words of the title equally prominent and
 visible.  You may add other material on the covers in addition.
 Copying with changes limited to the covers, as long as they preserve
 the title of the Document and satisfy these conditions, can be treated
 as verbatim copying in other respects.
 If the required texts for either cover are too voluminous to fit
 legibly, you should put the first ones listed (as many as fit
 reasonably) on the actual cover, and continue the rest onto adjacent
 pages.
 If you publish or distribute Opaque copies of the Document numbering
 more than 100, you must either include a machine-readable Transparent
 copy along with each Opaque copy, or state in or with each Opaque copy
 a computer-network location from which the general network-using
 public has access to download using public-standard network protocols
 a complete Transparent copy of the Document, free of added material.
 If you use the latter option, you must take reasonably prudent steps,
 when you begin distribution of Opaque copies in quantity, to ensure
 that this Transparent copy will remain thus accessible at the stated
 location until at least one year after the last time you distribute an
 Opaque copy (directly or through your agents or retailers) of that
 edition to the public.
 It is requested, but not required, that you contact the authors of the
 Document well before redistributing any large number of copies, to give
 them a chance to provide you with an updated version of the Document.
 \textbf{4. MODIFICATIONS}
 You may copy and distribute a Modified Version of the Document under
 the conditions of sections 2 and 3 above, provided that you release
 the Modified Version under precisely this License, with the Modified
 Version filling the role of the Document, thus licensing distribution
 and modification of the Modified Version to whoever possesses a copy
 of it.  In addition, you must do these things in the Modified Version:
 \begin{itemize}[leftmargin=*]
 \item[A.] Use in the Title Page (and on the covers, if any) a title distinct
 from that of the Document, and from those of previous versions
 (which should, if there were any, be listed in the History section
 of the Document).  You may use the same title as a previous version
 if the original publisher of that version gives permission.
 \item[B.] List on the Title Page, as authors, one or more persons or entities
 responsible for authorship of the modifications in the Modified
 Version, together with at least five of the principal authors of the
 Document (all of its principal authors, if it has fewer than five),
 unless they release you from this requirement.
 \item[C.] State on the Title page the name of the publisher of the
 Modified Version, as the publisher.
 \item[D.] Preserve all the copyright notices of the Document.
 \item[E.] Add an appropriate copyright notice for your modifications
 adjacent to the other copyright notices.
 \item[F.] Include, immediately after the copyright notices, a license notice
 giving the public permission to use the Modified Version under the
 terms of this License, in the form shown in the Addendum below.
 \item[G.] Preserve in that license notice the full lists of Invariant Sections
 and required Cover Texts given in the Document's license notice.
 \item[H.] Include an unaltered copy of this License.
 \item[I.] Preserve the section Entitled ``History'', Preserve its Title, and add
 to it an item stating at least the title, year, new authors, and
 publisher of the Modified Version as given on the Title Page.  If
 there is no section Entitled ``History'' in the Document, create one
 stating the title, year, authors, and publisher of the Document as
 given on its Title Page, then add an item describing the Modified
 Version as stated in the previous sentence.
 \item[J.] Preserve the network location, if any, given in the Document for
 public access to a Transparent copy of the Document, and likewise
 the network locations given in the Document for previous versions
 it was based on.  These may be placed in the ``History'' section.
 You may omit a network location for a work that was published at
 least four years before the Document itself, or if the original
 publisher of the version it refers to gives permission.
 \item[K.] For any section Entitled ``Acknowledgements'' or ``Dedications'',
 Preserve the Title of the section, and preserve in the section all
 the substance and tone of each of the contributor acknowledgements
 and/or dedications given therein.
 \item[L.] Preserve all the Invariant Sections of the Document,
 unaltered in their text and in their titles.  Section numbers
 or the equivalent are not considered part of the section titles.
 \item[M.] Delete any section Entitled ``Endorsements''.  Such a section
 may not be included in the Modified Version.
 \item[N.] Do not retitle any existing section to be Entitled ``Endorsements''
 or to conflict in title with any Invariant Section.
 \item[O.] Preserve any Warranty Disclaimers.
 \end{itemize}
 If the Modified Version includes new front-matter sections or
 appendices that qualify as Secondary Sections and contain no material
 copied from the Document, you may at your option designate some or all
 of these sections as invariant.  To do this, add their titles to the
 list of Invariant Sections in the Modified Version's license notice.
 These titles must be distinct from any other section titles.
 You may add a section Entitled ``Endorsements'', provided it contains
 nothing but endorsements of your Modified Version by various
 parties---for example, statements of peer review or that the text has
 been approved by an organization as the authoritative definition of a
 standard.
 You may add a passage of up to five words as a Front-Cover Text, and a
 passage of up to 25 words as a Back-Cover Text, to the end of the list
 of Cover Texts in the Modified Version.  Only one passage of
 Front-Cover Text and one of Back-Cover Text may be added by (or
 through arrangements made by) any one entity.  If the Document already
 includes a cover text for the same cover, previously added by you or
 by arrangement made by the same entity you are acting on behalf of,
 you may not add another; but you may replace the old one, on explicit
 permission from the previous publisher that added the old one.
 The author(s) and publisher(s) of the Document do not by this License
 give permission to use their names for publicity for or to assert or
 imply endorsement of any Modified Version.
 \textbf{5. COMBINING DOCUMENTS}
 You may combine the Document with other documents released under this
 License, under the terms defined in section~4 above for modified
 versions, provided that you include in the combination all of the
 Invariant Sections of all of the original documents, unmodified, and
 list them all as Invariant Sections of your combined work in its
 license notice, and that you preserve all their Warranty Disclaimers.
 The combined work need only contain one copy of this License, and
 multiple identical Invariant Sections may be replaced with a single
 copy.  If there are multiple Invariant Sections with the same name but
 different contents, make the title of each such section unique by
 adding at the end of it, in parentheses, the name of the original
 author or publisher of that section if known, or else a unique number.
 Make the same adjustment to the section titles in the list of
 Invariant Sections in the license notice of the combined work.
 In the combination, you must combine any sections Entitled ``History''
 in the various original documents, forming one section Entitled
 ``History''; likewise combine any sections Entitled ``Acknowledgements'',
 and any sections Entitled ``Dedications''.  You must delete all sections
 Entitled ``Endorsements''.
 \textbf{6. COLLECTIONS OF DOCUMENTS}
 You may make a collection consisting of the Document and other documents
 released under this License, and replace the individual copies of this
 License in the various documents with a single copy that is included in
 the collection, provided that you follow the rules of this License for
 verbatim copying of each of the documents in all other respects.
 You may extract a single document from such a collection, and distribute
 it individually under this License, provided you insert a copy of this
 License into the extracted document, and follow this License in all
 other respects regarding verbatim copying of that document.
 \textbf{7. AGGREGATION WITH INDEPENDENT WORKS}
 A compilation of the Document or its derivatives with other separate
 and independent documents or works, in or on a volume of a storage or
 distribution medium, is called an ``aggregate'' if the copyright
 resulting from the compilation is not used to limit the legal rights
 of the compilation's users beyond what the individual works permit.
 When the Document is included in an aggregate, this License does not
 apply to the other works in the aggregate which are not themselves
 derivative works of the Document.
 If the Cover Text requirement of section~3 is applicable to these
 copies of the Document, then if the Document is less than one half of
 the entire aggregate, the Document's Cover Texts may be placed on
 covers that bracket the Document within the aggregate, or the
 electronic equivalent of covers if the Document is in electronic form.
 Otherwise they must appear on printed covers that bracket the whole
 aggregate.
 \textbf{8. TRANSLATION}
 Translation is considered a kind of modification, so you may
 distribute translations of the Document under the terms of section~4.
 Replacing Invariant Sections with translations requires special
 permission from their copyright holders, but you may include
 translations of some or all Invariant Sections in addition to the
 original versions of these Invariant Sections.  You may include a
 translation of this License, and all the license notices in the
 Document, and any Warranty Disclaimers, provided that you also include
 the original English version of this License and the original versions
 of those notices and disclaimers.  In case of a disagreement between
 the translation and the original version of this License or a notice
 or disclaimer, the original version will prevail.
 If a section in the Document is Entitled ``Acknowledgements'',
 ``Dedications'', or ``History'', the requirement (section~4) to Preserve
 its Title (section~1) will typically require changing the actual
 title.
 \textbf{9. TERMINATION}
 You may not copy, modify, sublicense, or distribute the Document
 except as expressly provided under this License.  Any attempt
 otherwise to copy, modify, sublicense, or distribute it is void, and
 will automatically terminate your rights under this License.
 However, if you cease all violation of this License, then your license
 from a particular copyright holder is reinstated (a) provisionally,
 unless and until the copyright holder explicitly and finally
 terminates your license, and (b) permanently, if the copyright holder
 fails to notify you of the violation by some reasonable means prior to
 60 days after the cessation.
 Moreover, your license from a particular copyright holder is
 reinstated permanently if the copyright holder notifies you of the
 violation by some reasonable means, this is the first time you have
 received notice of violation of this License (for any work) from that
 copyright holder, and you cure the violation prior to 30 days after
 your receipt of the notice.
 Termination of your rights under this section does not terminate the
 licenses of parties who have received copies or rights from you under
 this License.  If your rights have been terminated and not permanently
 reinstated, receipt of a copy of some or all of the same material does
 not give you any rights to use it.
 \textbf{10. FUTURE REVISIONS OF THIS LICENSE}
 The Free Software Foundation may publish new, revised versions
 of the GNU Free Documentation License from time to time.  Such new
 versions will be similar in spirit to the present version, but may
 differ in detail to address new problems or concerns.  See
 \href{http://www.gnu.org/copyleft/}{http://www.gnu.org/copyleft/}.
 Each version of the License is given a distinguishing version number.
 If the Document specifies that a particular numbered version of this
 License ``or any later version'' applies to it, you have the option of
 following the terms and conditions either of that specified version or
 of any later version that has been published (not as a draft) by the
 Free Software Foundation.  If the Document does not specify a version
 number of this License, you may choose any version ever published (not
 as a draft) by the Free Software Foundation.  If the Document
 specifies that a proxy can decide which future versions of this
 License can be used, that proxy's public statement of acceptance of a
 version permanently authorizes you to choose that version for the
 Document.
 \textbf{11. RELICENSING}
 ``Massive Multiauthor Collaboration Site'' (or ``MMC Site'') means any
 World Wide Web server that publishes copyrightable works and also
 provides prominent facilities for anybody to edit those works.  A
 public wiki that anybody can edit is an example of such a server.  A
 ``Massive Multiauthor Collaboration'' (or ``MMC'') contained in the
 site means any set of copyrightable works thus published on the MMC
 site.
 ``CC-BY-SA'' means the Creative Commons Attribution-Share Alike 3.0
 license published by Creative Commons Corporation, a not-for-profit
 corporation with a principal place of business in San Francisco,
 California, as well as future copyleft versions of that license
 published by that same organization.
 ``Incorporate'' means to publish or republish a Document, in whole or
 in part, as part of another Document.
 An MMC is ``eligible for relicensing'' if it is licensed under this
 License, and if all works that were first published under this License
 somewhere other than this MMC, and subsequently incorporated in whole
 or in part into the MMC, (1) had no cover texts or invariant sections,
 and (2) were thus incorporated prior to November 1, 2008.
 The operator of an MMC Site may republish an MMC contained in the site
 under CC-BY-SA on the same site at any time before August 1, 2009,
 provided the MMC is eligible for relicensing.

 {\scriptsize \textbf{Preamble}}
 The GNU General Public License is a free, copyleft license for 
 software and other kinds of works.
 The licenses for most software and other practical works are designed 
 to take away your freedom to share and change the works. By contrast, 
 the GNU General Public License is intended to guarantee your freedom 
 to share and change all versions of a program--to make sure it 
 remains free software for all its users. We, the Free Software 
 Foundation, use the GNU General Public License for most of our 
 software; it applies also to any other work released this way by its 
 authors. You can apply it to your programs, too.
 When we speak of free software, we are referring to freedom, not 
 price. Our General Public Licenses are designed to make sure that you 
 have the freedom to distribute copies of free software (and charge 
 for them if you wish), that you receive source code or can get it if 
 you want it, that you can change the software or use pieces of it in 
 new free programs, and that you know you can do these things.
 To protect your rights, we need to prevent others from denying you 
 these rights or asking you to surrender the rights. Therefore, you 
 have certain responsibilities if you distribute copies of the 
 software, or if you modify it: responsibilities to respect the 
 freedom of others.
 For example, if you distribute copies of such a program, whether 
 gratis or for a fee, you must pass on to the recipients the same 
 freedoms that you received. You must make sure that they, too, 
 receive or can get the source code. And you must show them these 
 terms so they know their rights.
 Developers that use the GNU GPL protect your rights with two steps: 
 (1) assert copyright on the software, and (2) offer you this License 
 giving you legal permission to copy, distribute and/or modify it.
 For the developers' and authors' protection, the GPL clearly explains 
 that there is no warranty for this free software. For both users' and 
 authors' sake, the GPL requires that modified versions be marked as 
 changed, so that their problems will not be attributed erroneously to 
 authors of previous versions.
 Some devices are designed to deny users access to install or run 
 modified versions of the software inside them, although the 
 manufacturer can do so. This is fundamentally incompatible with the 
 aim of protecting users' freedom to change the software. The 
 systematic pattern of such abuse occurs in the area of products for 
 individuals to use, which is precisely where it is most unacceptable. 
 Therefore, we have designed this version of the GPL to prohibit the 
 practice for those products. If such problems arise substantially in 
 other domains, we stand ready to extend this provision to those 
 domains in future versions of the GPL, as needed to protect the 
 freedom of users.
 Finally, every program is threatened constantly by software patents. 
 States should not allow patents to restrict development and use of 
 software on general-purpose computers, but in those that do, we wish 
 to avoid the special danger that patents applied to a free program 
 could make it effectively proprietary. To prevent this, the GPL 
 assures that patents cannot be used to render the program non-free.
 The precise terms and conditions for copying, distribution and 
 modification follow.
 \bigskip
 {\scriptsize \textbf{TERMS AND CONDITIONS}}
 \textbf{0. Definitions.}
 ``This License'' refers to version 3 of the GNU General Public License.
 ``Copyright'' also means copyright-like laws that apply to other 
 kinds of works, such as semiconductor masks.
 ``The Program'' refers to any copyrightable work licensed under this 
 License. Each licensee is addressed as ``you''. ``Licensees'' and 
 ``recipients'' may be individuals or organizations.
 To ``modify'' a work means to copy from or adapt all or part of the 
 work in a fashion requiring copyright permission, other than the 
 making of an exact copy. The resulting work is called a ``modified 
 version'' of the earlier work or a work ``based on'' the earlier work.
 A ``covered work'' means either the unmodified Program or a work 
 based on the Program.
 To ``propagate'' a work means to do anything with it that, without 
 permission, would make you directly or secondarily liable for 
 infringement under applicable copyright law, except executing it on a 
 computer or modifying a private copy. Propagation includes copying, 
 distribution (with or without modification), making available to the 
 public, and in some countries other activities as well.
 To ``convey'' a work means any kind of propagation that enables other 
 parties to make or receive copies. Mere interaction with a user 
 through a computer network, with no transfer of a copy, is not 
 conveying.
 An interactive user interface displays ``Appropriate Legal Notices'' 
 to the extent that it includes a convenient and prominently visible 
 feature that (1) displays an appropriate copyright notice, and (2) 
 tells the user that there is no warranty for the work (except to the 
 extent that warranties are provided), that licensees may convey the 
 work under this License, and how to view a copy of this License. If 
 the interface presents a list of user commands or options, such as a 
 menu, a prominent item in the list meets this criterion.
 \textbf{1. Source Code.}
 The ``source code'' for a work means the preferred form of the work 
 for making modifications to it. ``Object code'' means any non-source 
 form of a work.
 A ``Standard Interface'' means an interface that either is an 
 official standard defined by a recognized standards body, or, in the 
 case of interfaces specified for a particular programming language, 
 one that is widely used among developers working in that language.
 The ``System Libraries'' of an executable work include anything, 
 other than the work as a whole, that (a) is included in the normal 
 form of packaging a Major Component, but which is not part of that 
 Major Component, and (b) serves only to enable use of the work with 
 that Major Component, or to implement a Standard Interface for which 
 an implementation is available to the public in source code form. A 
 ``Major Component'', in this context, means a major essential 
 component (kernel, window system, and so on) of the specific 
 operating system (if any) on which the executable work runs, or a 
 compiler used to produce the work, or an object code interpreter used 
 to run it.
 The ``Corresponding Source'' for a work in object code form means all 
 the source code needed to generate, install, and (for an executable 
 work) run the object code and to modify the work, including scripts 
 to control those activities. However, it does not include the work's 
 System Libraries, or general-purpose tools or generally available 
 free programs which are used unmodified in performing those 
 activities but which are not part of the work. For example, 
 Corresponding Source includes interface definition files associated 
 with source files for the work, and the source code for shared 
 libraries and dynamically linked subprograms that the work is 
 specifically designed to require, such as by intimate data 
 communication or control flow between those subprograms and other 
 parts of the work.
 The Corresponding Source need not include anything that users can 
 regenerate automatically from other parts of the Corresponding Source.
 The Corresponding Source for a work in source code form is that same 
 work.
 \textbf{2. Basic Permissions.}
 All rights granted under this License are granted for the term of 
 copyright on the Program, and are irrevocable provided the stated 
 conditions are met. This License explicitly affirms your unlimited 
 permission to run the unmodified Program. The output from running a 
 covered work is covered by this License only if the output, given its 
 content, constitutes a covered work. This License acknowledges your 
 rights of fair use or other equivalent, as provided by copyright law.
 You may make, run and propagate covered works that you do not convey, 
 without conditions so long as your license otherwise remains in 
 force. You may convey covered works to others for the sole purpose of 
 having them make modifications exclusively for you, or provide you 
 with facilities for running those works, provided that you comply 
 with the terms of this License in conveying all material for which 
 you do not control copyright. Those thus making or running the 
 covered works for you must do so exclusively on your behalf, under 
 your direction and control, on terms that prohibit them from making 
 any copies of your copyrighted material outside their relationship 
 with you.
 Conveying under any other circumstances is permitted solely under the 
 conditions stated below. Sublicensing is not allowed; section 10 
 makes it unnecessary.
 \textbf{3. Protecting Users' Legal Rights From Anti-Circumvention Law.}
 No covered work shall be deemed part of an effective technological 
 measure under any applicable law fulfilling obligations under article 
 11 of the WIPO copyright treaty adopted on 20 December 1996, or 
 similar laws prohibiting or restricting circumvention of such measures.
 When you convey a covered work, you waive any legal power to forbid 
 circumvention of technological measures to the extent such 
 circumvention is effected by exercising rights under this License 
 with respect to the covered work, and you disclaim any intention to 
 limit operation or modification of the work as a means of enforcing, 
 against the work's users, your or third parties' legal rights to 
 forbid circumvention of technological measures.
 \textbf{4. Conveying Verbatim Copies.}
 You may convey verbatim copies of the Program's source code as you 
 receive it, in any medium, provided that you conspicuously and 
 appropriately publish on each copy an appropriate copyright notice; 
 keep intact all notices stating that this License and any 
 non-permissive terms added in accord with section 7 apply to the 
 code; keep intact all notices of the absence of any warranty; and 
 give all recipients a copy of this License along with the Program.
 You may charge any price or no price for each copy that you convey, 
 and you may offer support or warranty protection for a fee.
 \textbf{5. Conveying Modified Source Versions.}
 You may convey a work based on the Program, or the modifications to 
 produce it from the Program, in the form of source code under the 
 terms of section 4, provided that you also meet all of these 
 conditions:
 \begin{itemize}[leftmargin=*]
 \item[a)] The work must carry prominent notices stating that you 
 modified it, and giving a relevant date.
 \item[b)] The work must carry prominent notices stating that it is 
 released under this License and any conditions added under section 7. 
 This requirement modifies the requirement in section 4 to ``keep 
 intact all notices''.
 \item[c)] You must license the entire work, as a whole, under this 
 License to anyone who comes into possession of a copy. This License 
 will therefore apply, along with any applicable section 7 additional 
 terms, to the whole of the work, and all its parts, regardless of how 
 they are packaged. This License gives no permission to license the 
 work in any other way, but it does not invalidate such permission if 
 you have separately received it.
 \item[d)] If the work has interactive user interfaces, each must 
 display Appropriate Legal Notices; however, if the Program has 
 interactive interfaces that do not display Appropriate Legal Notices, 
 your work need not make them do so.
 \end{itemize}
 A compilation of a covered work with other separate and independent 
 works, which are not by their nature extensions of the covered work, 
 and which are not combined with it such as to form a larger program, 
 in or on a volume of a storage or distribution medium, is called an 
 ``aggregate'' if the compilation and its resulting copyright are not 
 used to limit the access or legal rights of the compilation's users 
 beyond what the individual works permit. Inclusion of a covered work 
 in an aggregate does not cause this License to apply to the other 
 parts of the aggregate.
 \textbf{6. Conveying Non-Source Forms.}
 You may convey a covered work in object code form under the terms of 
 sections 4 and 5, provided that you also convey the machine-readable 
 Corresponding Source under the terms of this License, in one of these 
 ways:
 \begin{itemize}[leftmargin=*]
 \item[a)] Convey the object code in, or embodied in, a physical 
 product (including a physical distribution medium), accompanied by 
 the Corresponding Source fixed on a durable physical medium 
 customarily used for software interchange.
 \item[b)] Convey the object code in, or embodied in, a physical 
 product (including a physical distribution medium), accompanied by a 
 written offer, valid for at least three years and valid for as long 
 as you offer spare parts or customer support for that product model, 
 to give anyone who possesses the object code either (1) a copy of the 
 Corresponding Source for all the software in the product that is 
 covered by this License, on a durable physical medium customarily 
 used for software interchange, for a price no more than your 
 reasonable cost of physically performing this conveying of source, or 
 (2) access to copy the Corresponding Source from a network server at 
 no charge.
 \item[c)] Convey individual copies of the object code with a copy of 
 the written offer to provide the Corresponding Source. This 
 alternative is allowed only occasionally and noncommercially, and 
 only if you received the object code with such an offer, in accord 
 with subsection 6b.
 \item[d)] Convey the object code by offering access from a designated 
 place (gratis or for a charge), and offer equivalent access to the 
 Corresponding Source in the same way through the same place at no 
 further charge. You need not require recipients to copy the 
 Corresponding Source along with the object code. If the place to copy 
 the object code is a network server, the Corresponding Source may be 
 on a different server (operated by you or a third party) that 
 supports equivalent copying facilities, provided you maintain clear 
 directions next to the object code saying where to find the 
 Corresponding Source. Regardless of what server hosts the 
 Corresponding Source, you remain obligated to ensure that it is 
 available for as long as needed to satisfy these requirements.
 \item[e)] Convey the object code using peer-to-peer transmission, 
 provided you inform other peers where the object code and 
 Corresponding Source of the work are being offered to the general 
 public at no charge under subsection 6d.
 \end{itemize}
 A separable portion of the object code, whose source code is excluded 
 from the Corresponding Source as a System Library, need not be 
 included in conveying the object code work.
 A ``User Product'' is either (1) a ``consumer product'', which means 
 any tangible personal property which is normally used for personal, 
 family, or household purposes, or (2) anything designed or sold for 
 incorporation into a dwelling. In determining whether a product is a 
 consumer product, doubtful cases shall be resolved in favor of 
 coverage. For a particular product received by a particular user, 
 ``normally used'' refers to a typical or common use of that class of 
 product, regardless of the status of the particular user or of the 
 way in which the particular user actually uses, or expects or is 
 expected to use, the product. A product is a consumer product 
 regardless of whether the product has substantial commercial, 
 industrial or non-consumer uses, unless such uses represent the only 
 significant mode of use of the product.
 ``Installation Information'' for a User Product means any methods, 
 procedures, authorization keys, or other information required to 
 install and execute modified versions of a covered work in that User 
 Product from a modified version of its Corresponding Source. The 
 information must suffice to ensure that the continued functioning of 
 the modified object code is in no case prevented or interfered with 
 solely because modification has been made.
 If you convey an object code work under this section in, or with, or 
 specifically for use in, a User Product, and the conveying occurs as 
 part of a transaction in which the right of possession and use of the 
 User Product is transferred to the recipient in perpetuity or for a 
 fixed term (regardless of how the transaction is characterized), the 
 Corresponding Source conveyed under this section must be accompanied 
 by the Installation Information. But this requirement does not apply 
 if neither you nor any third party retains the ability to install 
 modified object code on the User Product (for example, the work has 
 been installed in ROM).
 The requirement to provide Installation Information does not include 
 a requirement to continue to provide support service, warranty, or 
 updates for a work that has been modified or installed by the 
 recipient, or for the User Product in which it has been modified or 
 installed. Access to a network may be denied when the modification 
 itself materially and adversely affects the operation of the network 
 or violates the rules and protocols for communication across the 
 network.
 Corresponding Source conveyed, and Installation Information provided, 
 in accord with this section must be in a format that is publicly 
 documented (and with an implementation available to the public in 
 source code form), and must require no special password or key for 
 unpacking, reading or copying.
 \textbf{7. Additional Terms.}
 ``Additional permissions'' are terms that supplement the terms of 
 this License by making exceptions from one or more of its conditions. 
 Additional permissions that are applicable to the entire Program 
 shall be treated as though they were included in this License, to the 
 extent that they are valid under applicable law. If additional 
 permissions apply only to part of the Program, that part may be used 
 separately under those permissions, but the entire Program remains 
 governed by this License without regard to the additional permissions.
 When you convey a copy of a covered work, you may at your option 
 remove any additional permissions from that copy, or from any part of 
 it. (Additional permissions may be written to require their own 
 removal in certain cases when you modify the work.) You may place 
 additional permissions on material, added by you to a covered work, 
 for which you have or can give appropriate copyright permission.
 Notwithstanding any other provision of this License, for material you 
 add to a covered work, you may (if authorized by the copyright 
 holders of that material) supplement the terms of this License with 
 terms:
 \begin{itemize}[leftmargin=*]
 \item[a)] Disclaiming warranty or limiting liability differently from 
 the terms of sections 15 and 16 of this License; or
 \item[b)] Requiring preservation of specified reasonable legal 
 notices or author attributions in that material or in the Appropriate 
 Legal Notices displayed by works containing it; or
 \item[c)] Prohibiting misrepresentation of the origin of that 
 material, or requiring that modified versions of such material be 
 marked in reasonable ways as different from the original version; or
 \item[d)] Limiting the use for publicity purposes of names of 
 licensors or authors of the material; or
 \item[e)] Declining to grant rights under trademark law for use of 
 some trade names, trademarks, or service marks; or
 \item[f)] Requiring indemnification of licensors and authors of that 
 material by anyone who conveys the material (or modified versions of 
 it) with contractual assumptions of liability to the recipient, for 
 any liability that these contractual assumptions directly impose on 
 those licensors and authors.
 \end{itemize}
 All other non-permissive additional terms are considered ``further 
 restrictions'' within the meaning of section 10. If the Program as 
 you received it, or any part of it, contains a notice stating that it 
 is governed by this License along with a term that is a further 
 restriction, you may remove that term. If a license document contains 
 a further restriction but permits relicensing or conveying under this 
 License, you may add to a covered work material governed by the terms 
 of that license document, provided that the further restriction does 
 not survive such relicensing or conveying.
 If you add terms to a covered work in accord with this section, you 
 must place, in the relevant source files, a statement of the 
 additional terms that apply to those files, or a notice indicating 
 where to find the applicable terms.
 Additional terms, permissive or non-permissive, may be stated in the 
 form of a separately written license, or stated as exceptions; the 
 above requirements apply either way.
 \textbf{8. Termination.}
 You may not propagate or modify a covered work except as expressly 
 provided under this License. Any attempt otherwise to propagate or 
 modify it is void, and will automatically terminate your rights under 
 this License (including any patent licenses granted under the third 
 paragraph of section 11).
 However, if you cease all violation of this License, then your 
 license from a particular copyright holder is reinstated (a) 
 provisionally, unless and until the copyright holder explicitly and 
 finally terminates your license, and (b) permanently, if the 
 copyright holder fails to notify you of the violation by some 
 reasonable means prior to 60 days after the cessation.
 Moreover, your license from a particular copyright holder is 
 reinstated permanently if the copyright holder notifies you of the 
 violation by some reasonable means, this is the first time you have 
 received notice of violation of this License (for any work) from that 
 copyright holder, and you cure the violation prior to 30 days after 
 your receipt of the notice.
 Termination of your rights under this section does not terminate the 
 licenses of parties who have received copies or rights from you under 
 this License. If your rights have been terminated and not permanently 
 reinstated, you do not qualify to receive new licenses for the same 
 material under section 10.
 \textbf{9. Acceptance Not Required for Having Copies.}
 You are not required to accept this License in order to receive or 
 run a copy of the Program. Ancillary propagation of a covered work 
 occurring solely as a consequence of using peer-to-peer transmission 
 to receive a copy likewise does not require acceptance. However, 
 nothing other than this License grants you permission to propagate or 
 modify any covered work. These actions infringe copyright if you do 
 not accept this License. Therefore, by modifying or propagating a 
 covered work, you indicate your acceptance of this License to do so.
 \textbf{10. Automatic Licensing of Downstream Recipients.}
 Each time you convey a covered work, the recipient automatically 
 receives a license from the original licensors, to run, modify and 
 propagate that work, subject to this License. You are not responsible 
 for enforcing compliance by third parties with this License.
 An ``entity transaction'' is a transaction transferring control of an 
 organization, or substantially all assets of one, or subdividing an 
 organization, or merging organizations. If propagation of a covered 
 work results from an entity transaction, each party to that 
 transaction who receives a copy of the work also receives whatever 
 licenses to the work the party's predecessor in interest had or could 
 give under the previous paragraph, plus a right to possession of the 
 Corresponding Source of the work from the predecessor in interest, if 
 the predecessor has it or can get it with reasonable efforts.
 You may not impose any further restrictions on the exercise of the 
 rights granted or affirmed under this License. For example, you may 
 not impose a license fee, royalty, or other charge for exercise of 
 rights granted under this License, and you may not initiate 
 litigation (including a cross-claim or counterclaim in a lawsuit) 
 alleging that any patent claim is infringed by making, using, 
 selling, offering for sale, or importing the Program or any portion 
 of it.
 \textbf{11. Patents.}
 A ``contributor'' is a copyright holder who authorizes use under this 
 License of the Program or a work on which the Program is based. The 
 work thus licensed is called the contributor's ``contributor version''.
 A contributor's ``essential patent claims'' are all patent claims 
 owned or controlled by the contributor, whether already acquired or 
 hereafter acquired, that would be infringed by some manner, permitted 
 by this License, of making, using, or selling its contributor 
 version, but do not include claims that would be infringed only as a 
 consequence of further modification of the contributor version. For 
 purposes of this definition, ``control'' includes the right to grant 
 patent sublicenses in a manner consistent with the requirements of 
 this License.
 Each contributor grants you a non-exclusive, worldwide, royalty-free 
 patent license under the contributor's essential patent claims, to 
 make, use, sell, offer for sale, import and otherwise run, modify and 
 propagate the contents of its contributor version.
 In the following three paragraphs, a ``patent license'' is any 
 express agreement or commitment, however denominated, not to enforce 
 a patent (such as an express permission to practice a patent or 
 covenant not to sue for patent infringement). To ``grant'' such a 
 patent license to a party means to make such an agreement or 
 commitment not to enforce a patent against the party.
 If you convey a covered work, knowingly relying on a patent license, 
 and the Corresponding Source of the work is not available for anyone 
 to copy, free of charge and under the terms of this License, through 
 a publicly available network server or other readily accessible 
 means, then you must either (1) cause the Corresponding Source to be 
 so available, or (2) arrange to deprive yourself of the benefit of 
 the patent license for this particular work, or (3) arrange, in a 
 manner consistent with the requirements of this License, to extend 
 the patent license to downstream recipients. ``Knowingly relying'' 
 means you have actual knowledge that, but for the patent license, 
 your conveying the covered work in a country, or your recipient's use 
 of the covered work in a country, would infringe one or more 
 identifiable patents in that country that you have reason to believe 
 are valid.
 If, pursuant to or in connection with a single transaction or 
 arrangement, you convey, or propagate by procuring conveyance of, a 
 covered work, and grant a patent license to some of the parties 
 receiving the covered work authorizing them to use, propagate, modify 
 or convey a specific copy of the covered work, then the patent 
 license you grant is automatically extended to all recipients of the 
 covered work and works based on it.
 A patent license is ``discriminatory'' if it does not include within 
 the scope of its coverage, prohibits the exercise of, or is 
 conditioned on the non-exercise of one or more of the rights that are 
 specifically granted under this License. You may not convey a covered 
 work if you are a party to an arrangement with a third party that is 
 in the business of distributing software, under which you make 
 payment to the third party based on the extent of your activity of 
 conveying the work, and under which the third party grants, to any of 
 the parties who would receive the covered work from you, a 
 discriminatory patent license (a) in connection with copies of the 
 covered work conveyed by you (or copies made from those copies), or 
 (b) primarily for and in connection with specific products or 
 compilations that contain the covered work, unless you entered into 
 that arrangement, or that patent license was granted, prior to 28 
 March 2007.
 Nothing in this License shall be construed as excluding or limiting 
 any implied license or other defenses to infringement that may 
 otherwise be available to you under applicable patent law.
 \textbf{12. No Surrender of Others' Freedom.}
 If conditions are imposed on you (whether by court order, agreement 
 or otherwise) that contradict the conditions of this License, they do 
 not excuse you from the conditions of this License. If you cannot 
 convey a covered work so as to satisfy simultaneously your 
 obligations under this License and any other pertinent obligations, 
 then as a consequence you may not convey it at all. For example, if 
 you agree to terms that obligate you to collect a royalty for further 
 conveying from those to whom you convey the Program, the only way you 
 could satisfy both those terms and this License would be to refrain 
 entirely from conveying the Program.
 \textbf{13. Use with the GNU Affero General Public License.}
 Notwithstanding any other provision of this License, you have 
 permission to link or combine any covered work with a work licensed 
 under version 3 of the GNU Affero General Public License into a 
 single combined work, and to convey the resulting work. The terms of 
 this License will continue to apply to the part which is the covered 
 work, but the special requirements of the GNU Affero General Public 
 License, section 13, concerning interaction through a network will 
 apply to the combination as such.
 \textbf{14. Revised Versions of this License.}
 The Free Software Foundation may publish revised and/or new versions 
 of the GNU General Public License from time to time. Such new 
 versions will be similar in spirit to the present version, but may 
 differ in detail to address new problems or concerns.
 Each version is given a distinguishing version number. If the Program 
 specifies that a certain numbered version of the GNU General Public 
 License ``or any later version'' applies to it, you have the option 
 of following the terms and conditions either of that numbered version 
 or of any later version published by the Free Software Foundation. If 
 the Program does not specify a version number of the GNU General 
 Public License, you may choose any version ever published by the Free 
 Software Foundation.
 If the Program specifies that a proxy can decide which future 
 versions of the GNU General Public License can be used, that proxy's 
 public statement of acceptance of a version permanently authorizes 
 you to choose that version for the Program.
 Later license versions may give you additional or different 
 permissions. However, no additional obligations are imposed on any 
 author or copyright holder as a result of your choosing to follow a 
 later version.
 \textbf{15. Disclaimer of Warranty.}
 THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY 
 APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT 
 HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM ``AS IS'' WITHOUT 
 WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT 
 LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR 
 A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND 
 PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE 
 DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR 
 CORRECTION.
 \textbf{16. Limitation of Liability.}
 IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING 
 WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR 
 CONVEYS THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, 
 INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES 
 ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT 
 NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR

 {\scriptsize \textbf{How to Apply These Terms to Your New Programs}}
 If you develop a new program, and you want it to be of the greatest 
 possible use to the public, the best way to achieve this is to make 
 it free software which everyone can redistribute and change under 
 these terms.
 To do so, attach the following notices to the program. It is safest 
 to attach them to the start of each source file to most effectively 
 state the exclusion of warranty; and each file should have at least 
 the ``copyright'' line and a pointer to where the full notice is found.
 \begingroup
 \leftskip=2em
 \slshape
 <one line to give the program's name and a brief idea of what it does.>\\

 along with this program.  If not, see 
 \href{http://www.gnu.org/licenses/}{http://www.gnu.org/licenses/}.
 \endgroup
 Also add information on how to contact you by electronic and paper 
 mail.
 If the program does terminal interaction, make it output a short 
 notice like this when it starts in an interactive mode:
 \begingroup
 \leftskip=2em
 \slshape
 <program>  Copyright (C) <year>  <name of author>\\
 This program comes with ABSOLUTELY NO WARRANTY; for details type 
 `show w'.
 This is free software, and you are welcome to redistribute it
 under certain conditions; type `show c' for details.
 \endgroup
 The hypothetical commands `show w' and `show c' should show the 
 appropriate parts of the General Public License. Of course, your 
 program's commands might be different; for a GUI interface, you would 
 use an ``about box''.
 You should also get your employer (if you work as a programmer) or 
 school, if any, to sign a ``copyright disclaimer'' for the program, 
 if necessary. For more information on this, and how to apply and 
 follow the GNU GPL, see 
 \href{http://www.gnu.org/licenses/}{http://www.gnu.org/licenses/}.
 The GNU General Public License does not permit incorporating your 
 program into proprietary programs. If your program is a subroutine 
 library, you may consider it more useful to permit linking 
 proprietary applications with the library. If this is what you want 
 to do, use the GNU Lesser General Public License instead of this 
 License. But first, please read

 \chapter{Getting Started}
 Because of the wide variety of hardware combinations, there is no "one 
 case fits all" approach to getting started.  The good news is that RomWBW 
 operates very consistently regardless of the specific hardware.  The 
 operating systems, applications, and storage formats are all common.  
 However, building and testing your hardware is entirely outside the scope 
 of this document.  The RetroBrew Computing Forum 
 (https://www.retrobrewcomputers.org/forum) is probably the best place to 
 get advice if you get stuck on hardware issues.
 \section{SIMH Simulator}
 It is not necessary, but I highly recommend running RomWBW under the SIMH 
 Simulator as a first step.  This requires no hardware and will allow you 
 to see how it should look when you use it on real hardware.  Since the 
 SIMH software is included in the distribution package, you can start it 
 with a single command.  Using a command prompt window, navigate to the 
 high level directory of the distribution.  Enter the command "sim" and 
 the simulator should start up.  The first few lines of output should
 look similar to Figure \ref{fig:simhboot}.  You may see some benign
 warning messages that can be ignored.

 \end{Verbatim}
 \caption{SIMH Boot Example}
 \label{fig:simhboot}
 \end{figure}
 \section{Board Setup}
 In all cases, you will want to start with a Z80/Z180 host board.  Any of 
 the boards listed in System Requirements will work fine.  I strongly 
 recommend that you initially work on getting just the single host board 
 running by itself -- don't even plug it into an ECB backplane.
 Given a host board that is assembled and passes any hardware checks 
 recommended by the boards designer, you need to make sure the board is 
 configured for RomWBW.  Refer to the entry in Appendix A for your board 
 and confirm that all switches and jumpers on the board are set as 
 required by RomWBW.
 Your initial goal is to locate and program a ROM image for your host 
 board.  The ROM images are located in the Output directory.  You are 
 looking for the files that end in ".rom".  Don't worry about all of the 
 other variations at this point.  Refer to Table \ref{tab:basicromfiles} to 
 determine the ROM image that you want.
 \begin{table}[ht]
 \center
 %\renewcommand{\arraystretch}{1.5}
 \setlength{\arrayrulewidth}{2pt}
 \begin{tabular}{l l}
 \toprule
 \bf CPU Board & \bf ROM Image File \\
 \midrule
 SBC v1/v2 & SBC\_std.rom \\
 Zeta v1	 & ZETA\_std.rom \\
 Zeta v2	 & ZETA2\_std.rom \\
 N8 (2511) & N8\_2511.rom \\
 N8 (2312) & N8\_2312.rom \\
 Mark IV & MK4\_std.rom \\
 \bottomrule
 \end{tabular}
 \caption{Basic ROM Files}
 \label{tab:basicromfiles}
 \end{table}
 Locate the appropriate ROM image file in the Output directory based on 
 Table \ref{tab:basicromfiles}.  You should see that the file is exactly 512KB in size.  
 As indicated above in System Requirements, your system should have a ROM 
 capacity of 512KB or greater.  You need to program the file to your ROM 
 using whatever tool you have.  Programming a ROM chip is beyond the scope 
 of this document, but any feel free to ask for help at the RetroBrew 
 Computing Forum.  The ROM image files are pure binary and should be 
 programmed into the ROM chip starting at address 0H thru address 7FFFH (8000H bytes).  
 Insert the programmed ROM chip in your system.
 Initially, you will need two external connections to your board.  Power 
 and serial port.  All of the CPU boards provide an onboard power 
 connection.  Refer to the board designer's notes on the RBC Wiki for more 
 information on the power connection your board requires.
 Finally, you must connect the primary serial port of your host board to a 
 terminal using 38,400 baud, 8 data bits, 1 stop bit, and no parity.  You can 
 use either a dedicated terminal or use terminal emulation software on 
 your PC\footnote{Under Windows, Tera Term is a good choice for terminal
 emulation.}.
 When connecting to a standard PC serial port, a null modem cable is required.
 There is a good document on the Wiki that explains cabling of serial ports at 
 http://???????. \todo{Need to restore serial port cabling document on Wiki!}
 \section{Startup}
 System startup (booting) is accomplished simply by applying power.  In some cases,
 it may be necessary to press the reset button after applying power to get a
 successful startup.
 If everything is working properly, you should see something like Figure \ref{fig:boot}
 on your terminal screen.  Your output will vary somewhat depending on your
 specific hardware.  The example shown comes from a Mark IV.

 \caption{Typical Boot Display}
 \label{fig:boot}
 \end{figure}
 If you see output on your terminal screen, but it is garbled/unreadable, then
 check the serial port configuration settings on your terminal or terminal
 emulation software.
 If you do not see any output of any kind on your terminal screen, the following
 general areas should be checked:
 \begin{itemize}
 \item Confirm power is being applied to the board and the the voltage is
 in an acceptable range.
 \item Confirm the ROM is programmed accurately by placing it back in the
 programmer and using the verify function.
 \item Verify the serial connection.  When connecting to a PC, make sure
 you have a null modem cable or adapter.
 \item Review your board's construction carefully for chip orientation, bent
 pins, missing or bridged solder joints, etc.
 \end{itemize}
 You will find that the RetroBrew Computing Group is very helpful if you get
 stuck.  The best way to request assistance is to post a message on the
 Forum.
 \section{Boot Display}
 As illustrated in Figure \ref{fig:boot}, RomWBW displays a lot of information
 about the system and it's configuration.  There are 4 basic sections to
 the boot display.
 Line 1 is a banner that identifies the BIOS portion of the ROM including
 version and build date.
 Lines 3-12 display the hardware inventory of the system as understood by
 the ROM.  Note that some of this information is \emph{not} discovered dynamically --
 it is built into the ROM.  So, do not be alarmed if some parts of this
 display do not match your hardware.  For example, the RAM and ROM size
 are configured into the ROM itself.  You can refer to Appendix A for
 more information on how to read the specific lines.
 Lines 14-22 contain a table that summarizes the devices in the system.  This 
 information is used when the operating system is loaded/configured to 
 assign OS devices to system devices.
 Lines 24-27 is the display of the boot loader menu and prompt.  The boot
 loader allows you to choose the operating mode you want to initiate.  These
 options will be described the next section.
 \section{Loader}
 At the conclusion of a successful system startup, the loader menu/prompt will
 be displayed on the console.  The function of the loader is to load an
 operating system or system monitor.
 \subsection{Monitor}
 Pressing 'M' at the boot loader prompt will launch a basic system monitor.
 The system monitor provides very basic functions that are primarily useful
 for testing components of your system.  These functions include displaying
 and modifying memory, reading and writing to I/O ports, etc.
 Refer to ??? for monitor operation.
 \subsection{CP/M}
 Pressing 'C' at the boot loader prompt will launch Digital Research CP/M-80
 Version 2.2.  A complete copy of the CP/M operating system is imbedded in
 the ROM and will be loaded directly from there, so no disk access is required.
 Initially, drive A will be a RAM drive (initialized with no files).  Drive B
 will be a ROM drive.  The standard CP/M distribtion files are included on the
 ROM drive (e.g., ASM, PIP, STAT).  Drive B will initially be the logged drive.
 At this point, you can execute the programs on drive B.  Remember that drive B
 is a ROM drive, so any attempt to write to that drive will result in an error.
 Refer to Chapter ?? for more information on using CP/M 2.2.
 \subsection{Z-System}
 Pressing 'Z' at the boot loader prompt will launch Z-System, a CP/M 2.2
 compatible operating system with many enhancements.  As with CP/M, this
 operating system will be loaded directly from ROM.
 The drive configuration for Z-System is identical to CP/M.
 Refer to Chapter ?? for more information on using Z-System.
 \subsection{Disk Boot}
 The boot loader also supports loading an operating system from a disk
 device.  In this case, you must press the number key corresponding to
 the disk device containing the operating system to be loaded.  The
 disk device numbers are the ones listed in the device summary table.
 In order to boot from a disk device, it must be properly initialized
 using the SYSCOPY application or equivalent.  Attempting to boot a
 disk that has no operating system will result in an error and the
 boot loader prompt will be redisplayed.
 You can press 'L' at the boot loader prompt to display a list of
 the disk devices available.  The existence of a disk in this list
 does \emph{not} mean that it has been initialized with an
 operating system.

 \chapter{Overview}
 RomWBW is system software that supports the Z80/Z180 based computing 
 platforms produced by the RetroBrew 
 Computing Group which is found at http://www.retrobrewcomputers.org.  The goal of the 
 project is to provide all firmware 
 and software needed to make a fully functional computing platform.  This 
 includes both firmware (ROM) and 
 software (disk images).  The source code is provided and is licensed under 
 GPL v3.  A GitHub repository is 
 used to maintain all source code and can be found at 
 http://www.github.com/RomWBW.
 Essentially all Z80/Z180 based hardware produced by RetroBrew Computing is 
 fully supported by RomWBW.  Much of the software was adapted from software 
 produced by others in the community (see Acknowledgements) and is packaged 
 within RomWBW to provide an integrated solution.  A companion document 
 (RomWBW System Guide) provides substantial detail on the architecture and 
 internal operation of this software.
 It is worth noting that this software is a perpetual work-in-progress.  
 While it has become fairly stable and robust over time, it is undergoing 
 constant updates to support new and revised hardware produced by the 
 community.  Backward compatibility between releases should not be assumed.
 In order to provide a complete solution, the RomWBW package incorporates a 
 hardware BIOS (hardware drivers) and selected operating systems and 
 application software.  All software is derived from the CP/M era of 8-bit 
 computing.  The operating systems included have been adapted to run under 
 the RomWBW architecture.  In general, application software has simply been 
 included as originally distributed by the vendors and required no adaptation.
 The RomWBW distribution package includes all the tools required to easily 
 build the software from the source that is included in the package.  The 
 package includes a range of pre-built ROM and disk images.  These are 
 usually sufficient to get your hardware up and running simply by 
 programming a ROM and optionally copying disk image(s) to a floppy disk, CF 
 Card, or SD Card.  If you wish to highly customize your system software, it 
 is straightforward to modify the source code and build your own.  At 
 present, this requires Microsoft Windows XP or greater.  All of the tools 
 have counterparts for Linux, so building the software under Linux should be 
 possible with a little effort.
 \section{System Requirements}
 RomWBW is purely a software project.  It assumes you have a fully 
 functional hardware platform on which to host the software.  A great deal 
 of information on procuring and building the appropriate hardware is found 
 on the RetroBrew Computing Wiki at http://www.retrobrewcomputing.org.  
 Additionally, the RetroBrew Computing Group has a very active forum found at 
 http://www.retrobrewcomputing.org/forum.  This forum is the ideal place to 
 ask questions and get guidance for hardware and software.  It is the 
 primary forum for supporting RomWBW.
 The starting point for a hardware platform that will appropriately host 
 RomWBW software is one of the following CPU boards:
 \begin{description}[style=multiline, leftmargin=1.25in, labelindent=0.25in, align=right]
 \item [SBC]
 This is the original Z80 CPU board produced by the community.  It remains a 
 very functional platform and is relatively easy to build.  Note that v1 has 
 a design deficiency that may or may not prevent the proper operation of 
 RomWBW (bank switching does not always function reliably).  The SBC CPU 
 board features an ECB bus connector which allows it to be expanded with a 
 backplane and peripheral boards.
 \item [Zeta]
 The Zeta is very similar to the SBC board and is generally compatible with 
 it.  However, the Zeta platform is optimized to be a compact, standalone 
 system.  In addition to the features of the SBC, it includes an onboard 
 floppy disk controller and the form factor of the board allows it to be 
 mounted directly to a 3.5" floppy disk for a complete computing solution.  
 It optionally supports a single daughter board that provides SD Card 
 storage, VGA Monitor interface, and PS/2 keyboard interface.  Although it 
 does not have a bus interface, Zeta is powerful, compact, and fully 
 featured.  The Zeta v2 primarily adds enhanced bank switching and an 
 interrupt controller which is not required by RomWBW.
 \item [N8]
 The N8 is a very robust SBC.  It is significantly larger than the SBC and 
 incorporates a wide range of peripherals right on the one board (although 
 it also supports expansion via ECB bus).  The N8 is based on the Z180 CPU 
 and incorporates interfaces for 2 serial ports, 2 parallel ports, IDE Hard 
 Disk / CF Card, SD Card, sound synthesizer, video display, PS/2 keyboard 
 and mouse interface, and floppy disk controller.  This board is very 
 powerful, but more challenging to build.  It is not compatible with the 
 SBC/Zeta -- it implements a different bank switching mechanism.
 \item [Mark IV]
 The Mark IV by John Coffman is similar to the SBC in that it shares the 
 same form factor and ECB for expansion.  However, it is substantially more 
 powerful featuring a Z180 CPU and onboard CF Card and SD Card interfaces.
 \end{description}
 RomWBW fully supports all of the above boards as a starting point.    For 
 Zeta, the ParPortProp is supported as an option.  The other platforms all 
 support the ECB bus for adding optional peripheral support boards.
 In addition to the hardware listed above, RomWBW also runs well on the 
 Microsoft Windows based SIMH Altair Z80 simulator which allows you to try 
 all of the RomWBW features without any actual hardware.  The distribution 
 package contains a copy of the simulator software for MS Windows, so it is 
 very easy to use it (see Getting Started).
 Note that RomWBW assumes specific board configuration settings.  You must 
 ensure that you set the jumpers/switches of each board as required by 
 RomWBW (unless you modify RomWBW and produce a custom version that supports 
 your specific board configurations).  The standard board configuration 
 settings are documented in Appendix A.
 Note that RomWBW assumes there is 512KB of ROM and 512KB of RAM for all 
 systems.  It is fine if your system has more RAM or ROM than this, but it 
 is problematic if you have less.  It would be very rare for a system to 
 have less that these amounts, but be aware of this constraint.  These 
 assumptions can be modified via customization later, but the pre-built 
 software must have these minimums.
 All of the host boards include a serial port.  RomWBW will use this serial 
 port for output when you start your system.  By default, RomWBW uses 38,400 
 baud, 8 data bits, 1 stop bit, and no parity.  You will need to connect the 
 primary serial port of the host board to a terminal (or PC running terminal 
 emulation software) to see the system output when you start RomWBW.
 The use of the ECB bus signals is standardized such that any ECB add-on 
 board can generally be combined with any of the ECB host boards to provide 
 enhanced functionality.  Appendix A provides an inventory of the boards 
 supported by RomWBW along with relevant notes and required board 
 configuration settings.  Appendix A also includes a compatibility/support 
 matrix between the host boards and the peripheral support boards.
 \section{Acknowledgements}
 First, I want to be clear that RomWBW is not the only option available for 
 system software on RetroBrew Computing Z80/Z180 hardware.  While many 
 similar projects are no longer active, they are very useful and may contain 
 functionality that has not been incorporated in RomWBW.  All of the 
 software projects (including RomWBW) are listed in the RetroBrew Computing 
 Wiki.
 The UNA Project from John Coffman is the other currently active software 
 project for the Z80/Z180 projects.  It is far more advanced than RomWBW in 
 that it can support all 4 host boards with a single ROM image and allows 
 dynamic system configuration via onboard setup.  It does not yet support 
 the full range of hardware or video capabilities of RomWBW.  Note that 
 RomWBW supports an UNA "hybrid" configuration in which the UNA BIOS is 
 combined with the RomWBW OS and application layers.
 The RetroBrew Computing Group has existed in various forms since about 2010 
 (?).  Many individuals have contributed to the community.  The original 
 founder of the community has moved on and requested anonymity going 
 forward.  However, his initiative is greatly appreciated.  While there is 
 no formal structure to the community, Andrew Bingham has taken the mantle 
 of responsibility for the wiki and discussion group.  This is a critical 
 function and he deserves substantial credit for this effort.
 Earlier in the community's history, there were multiple branches of 
 software development.  Frequently, when a new board was produced, someone 
 would create an independent code branch to support it.  This started to 
 lead to a very fragmented set of software that made it very difficult to 
 create an integrated system with selected boards.  RomWBW came about as an 
 effort to create a framework that would allow arbitrary hardware to be 
 easily added without creating entirely separate branches of code.
 RomWBW essentially became a semi-structured place to incorporate all of the 
 many software efforts of the community.  Initially, most of the RomWBW 
 codebase was simply a "cut and paste" of the software produced by others.  
 Over time, much of this software has been repeatedly revised such that it 
 is no longer similar to the original, but RomWBW owes its existence to the 
 contributions of many other individuals.  A few of those people are listed 
 below and I apologize for anyone that I may have inadvertently omitted.  I 
 have intentionally omitted the original founder of the community based on 
 my understanding of his desire to be anonymous going forward.
 Douglas Goodall worked in very close collaboration with me during the first 
 year of the RomWBW Project.  He produced an excellent set of supporting 
 utility programs and provided a great deal of design input.  Regrettably, 
 his utilities no longer have a caretaker and have become unusable as RomWBW 
 has evolved, but their legacy continues within the current codebase.  The 
 source for all of these utilities is still available if anyone wants to 
 take responsibility for bringing them back to current status.
 John Coffman has personally produced a great deal of the hardware designs 
 within the community.  RomWBW contains many portions of code that John 
 contributed over time.  Additionally, he has been instrumental in providing 
 advice and guidance to me for many years now.
 Dan Werner has been one of the most prolific coders within the community.  
 A great deal of his code was incorporated in the early RomWBW releases.  
 David Giles produced some code that also provided a more integrated set of 
 software for each host board.  Over time, much of his code was incorporated 
 in RomWBW.  Likewise, Max Scane has produced code that ultimately wound up 
 in RomWBW -- specifically, he contributed the CLRDIR application.
 It is my belief that all code incorporated into RomWBW has been done so 
 with the express or implied permission of the original authors.  I realize 
 there have been many other individuals that have contributed to RomWBW and 
 apologize for not naming all of them.
 \section{RomWBW Distribution Package}
 RomWBW is distributed as a complete package (a .zip file) that contains 
 everything appropriate for the different hardware variations.  In other 
 words, don't look for a specific distribution for your hardware, you just 
 want the current package.  Within the package, you will find documentation, 
 source code, build tools, and pre-built ROM and disk images.
 The distribution package is usually hosted at the following locations:
 \begin{itemize}
 \item {\bf RetroBrew Computing Wiki}
 Navigate to https://www.retrobrewcomputers.org.  Then, using the navigation 
 menu on the left, choose software $\rightarrow$ firmwareos
 $\rightarrow$ romwbw to reach the RomWBW 
 Project Page.  At the bottom of the page you will find the distribution 
 files listed for download.
 \item {\bf GitHub}
 Navigate to https://github.com/wwarthen/RomWBW for the RomWBW Project 
 on GitHub.  Select "releases" to reach the list of distribution files.  
 Note that you will see both Prereleases and Releases listed.  Unless you 
 specifically want to test work-in-progress, please download only a Release 
 version.
 \end{itemize}
 The package should be named something like RomWBW-2.8-Package.zip.  Using 
 any standard personal computer (Windows, Linux, Mac, etc.), download and 
 extract the contents of the zip file using any of the standard zip tools.  
 You will see that there are several directories that are used to organize 
 the contents.  Don't get overwhelmed.  Initially, all you really care about 
 is the Output directory (and possibly the Doc directory):
 \begin{description}[style=multiline, leftmargin=1.25in, labelindent=0.25in, align=right]
 \item [Doc]
 Contains documentation files for many components of the RomWBW distribution 
 including operating systems, applications, and other aspects of RomWBW 
 itself.  In most cases, the name of the file should identify the component 
 being documented.
 \item[Hardware]
 Files that are specific to certain hardware components.  For example, it 
 has the font ROM images for the video display boards.  You do not need any 
 of these files for the host boards used initially.  Appendix A describes 
 the contents of this directory for relevant boards.
 \item[Images]
 Files that are used to create disk images.  Since the disk images are all 
 pre-built, you do not need to worry about this directory until you want to 
 create custom disk images (documented later).
 \item[Output]
 The ROM and Disk Images that you need to get started as documented below in 
 Getting Started.
 \item[Source]
 The source code files that are compiled or assembled to create RomWBW.  
 Again, the output is pre-built, so you don't need to worry about this 
 directory until you want to customize your system.
 \item[Tools]
 Windows-based applications that are used to build RomWBW.  It also contains 
 applications that you can use to copy disk images to floppy disks, CF 
 Cards, SD Cards, etc.  It also has the SIMH simulation software.
 \end{description}
 In most cases, you will find a ReadMe.txt file in the directory which 
 describes the contents of the directory in more detail.
