+                    GNU GENERAL PUBLIC LICENSE
+                       Version 3, 29 June 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+                            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.
+
+                       TERMS AND CONDITIONS
+
+  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.
+
+  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.
+
+  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.
+
+  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.
+
+  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.
+
+  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:
+
+    a) The work must carry prominent notices stating that you modified
+    it, and giving a relevant date.
+
+    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".
+
+    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.
+
+    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.
+
+  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.
+
+  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:
+
+    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.
+
+    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.
+
+    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.
+
+    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.
+
+    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.
+
+  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.
+
+  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:
+
+    a) Disclaiming warranty or limiting liability differently from the
+    terms of sections 15 and 16 of this License; or
+
+    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
+
+    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
+
+    d) Limiting the use for publicity purposes of names of licensors or
+    authors of the material; or
+
+    e) Declining to grant rights under trademark law for use of some
+    trade names, trademarks, or service marks; or
+
+    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.
+
+  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.
+
+  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.
+
+  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.
+
+  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.
+
+  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.
+
+  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.
+
+  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.
+
+  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

+
+            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.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>

+    along with this program.  If not, see <http://www.gnu.org/licenses/>.
+
+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:
+
+    <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.
+
+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

+
+This directory ("Binary") is part of the RomWBW System Software 
+distribution archive.  It contains the completed binary outputs of 
+the build process.  As described below, these files are used to 
+assemble a working RetroBrew Computers system.
+
+The files in this directory are created by the build process that is 
+documented in the ReadMe.txt file in the Source directory.  When 
+released the directory is populated with the default output files.  
+However, the output of custom builds will be placed in this directory 
+as well.
+
+ROM Firmware Images (<plt>_<cfg>.rom)
+-------------------------------------
+
+The files with a ".rom" extension are binary images ready to program 
+into an appropriate PROM.  These files are named with the format 
+<plt>_<cfg>.rom. <plt> refers to the primary platform such as Zeta, 
+N8, Mark IV, etc.  <cfg> refers to the specific configuration.  When 
+released, there will be a standard configuration ("std") for each 
+platform.  So, for example, the file called MK4_std.rom is a ROM 
+image for the Mark IV with the standard configuration. If a custom 
+configuration called "custom" is created and built, a new file called 
+MK4_custom.rom will be added to this directory.
+
+Documentation of the pre-built ROM Images is contained in the 
+RomList.txt file.
+
+ROM Executable Images (<plt>_<cfg>.com)
+---------------------------------------
+
+When a ROM image (".rom") is created, an executable version of the 
+ROM is also created.  These files have the same naming convention as 
+the ROM Image files, but have the extension ".com".  These files can 
+be copied to a working system and run like a normal application.
+
+When run on the target system, they install in RAM just like they had 
+been programmed into the ROM.  This allows a new ROM build to be 
+tested without reprogramming the actual ROM.
+
+ROM Binary Images (<plt>_<cfg>.img)
+-----------------------------------
+
+Also when a ROM image is created, a third variation of the ROM is 
+created again with the same naming convention, but with the extension 
+of .img.  These files are similar to the .com files in that they can 
+be used to test a ROM build without actually programming a new ROM.  
+The .img files are specifically for loading via UNA from a FAT file 
+system.  The functionality of the UNA FAT file system loader is 
+beyond the scope of this document.
+
+VDU ROM Image (vdu.rom)
+-----------------------
+
+The VDU video board requires a dedicated onboard ROM containing the 
+font data.  The "vdu.rom" file contains the binary data to program 
+onto that chip.
+
+Disk Images (fd*.img, hd*.img)
+------------------------------
+
+RomWBW includes a mechanism for generating floppy disk and hard disk 
+binary images that are ready to copy directly to a floppy, hard disk, 
+CF Card, or SD Card which will then be ready for use in any 
+RomWBW-based system.
+
+Essentially, these files contain prepared floppy and hard disk images 
+with a large set of programs and related files.  By copying the 
+contents of these files to appropriate media as described below, you 
+can quickly create ready-to-use media.
+
+The fd*.img files are floppy disk images.  They are sized for 1.44MB 
+floppy media and can be copied to actual floppy disks using 
+RawWriteWin (as long as you have access to a floppy drive on your 
+Windows computer).  The resulting floppy disks will be usable on any 
+RomWBW-based system with floppy drive(s).
+
+Likewise, the hd*.img files are hard disk images.  Each file is 
+intended to be copied to the start of any type of hard disk media 
+(typically a CF Card or SD Card). The resulting media will be usable 
+on any RomWBW-based system that accepts the corresponding media type.
+
+Note that the contents of the floppy/hard disk images are created by 
+the BuildImages.cmd script in the Source directory.  Additional 
+information on how to generate custom disk images is found in the 
+Source\Images directory.
+
+Propeller ROM Images (*.eeprom)
+-------------------------------
+
+The files with and extension of ".eeprom" contain the binary images 
+to be programmed into the Propeller-based boards.  The list below 
+indicates which file targets each of the Propeller board variants:
+
+	ParPortProp	ParPortProp.eeprom
+	PropIO V1	PropIO.eeprom
+	PropIO V2	PropIO2.eeprom
+
+Refer to the board documentation of the boards for more information 
+on how to program the EEPROMs on these boards.

+
+This directory ("Binary") is part of the RomWBW System Software 
+distribution archive.  Refer to the ReadMe.txt file in this 
+directory for more information on the overall contents of the 
+directory.
+
+When distributed, RomWBW contains a set of pre-built ROM images that 
+are ready to program onto the EEPROM of any of the Z80/Z180 based 
+RetroBrew Computers CPU boards.  Additionally, any custom built ROM 
+images will be placed in this directory.
+
+All of the pre-built ROM images are 512KB.  This size is compatible 
+with all of the Z80/Z180 systems.  Some systems can accept different 
+size ROM images.  Creating alternative sizes requires a custom ROM 
+build (see ReadMe.txt in the Source directory).
+
+It is critical that the right ROM Imgae be selected for the target 
+platform being used.  The table below indicates the correct ROM 
+image to use for each platform:
+
+	SBC V1/V2	SBC_std.rom
+	Zeta V1		ZETA_std.rom
+	Zeta V2		ZETA2_std.rom
+	N8		N8_std.rom
+	Mark IV		MK4_std.rom
+
+You will find there is one additional ROM image called 
+"UNA_std.rom". This ROM image is an UNA-based RomWBW ROM image.  As 
+such, this ROM image can be used on any Z80/Z180 platform supported 
+by John Coffman's UNA BIOS.  Refer to RetroBrew Computers Wiki for 
+more information on UNA hardware support.
+
+For each of the ROM Images (".rom"), there are corresponding files 
+with the extensions of ".com" and ".img".  The .com variant can be 
+copied to a functional RomWBW-based system and executed like a 
+normal application under CP/M or Z-System. This will load the new 
+ROM on-the-fly.  It is an excellent way to test a ROM Image before 
+actually burning it.  Similarly, the .img files can be loaded using 
+the UNA FAT loader for testing.
+
+All of the standard ROM Images are configured with:
+ - 512KB ROM Disk
+ - 512KB RAM Disk
+ - 38.4Kbps baud serial console
+ - Auto-discovery of all serial ports
+
+All hard disk type devices (IDE, PPIDE, CF Card, SD Card) will be 
+automatically assigned two drive letters per device.  The drive 
+letters will refer to the first 2 slices of the device. The ASSIGN 
+command can be used to display and reassign drives to disk devices 
+and slices as desired.
+
+Standard ROM Image Notes
+------------------------
+
+The standard ROM images will detect and install support for certain 
+devices and peripherals that are on-board or frequently used with 
+each platform as documented below.  If the device or peripheral is 
+not detected at boot, the ROM will simply bypass support 
+appropriately.
+
+SBC:
+ - Includes support for PPIDE/CF Card(s) connected to on-board    
+   parallel port.
+ - Includes support for CVDU and VGA3 boards.  If detected at
+   startup, support for video and keyboard is installed
+   including VT-100/ANSI terminal emulation.
+ - Auto-detects PropIO or PropIO V2 and installs associated
+   video, keyboard and SD Card support if present.
+ - If PropIO, PropIO V2, CVDU, or VGA hardware is detected,
+   initial console output is determined by JP2.  If JP2 is
+   shorted, console will go to on-board serial port, if JP2
+   is open, console will go to the detected video and keyboard
+   ports.
+ - SBC V1 has a known race condition in the bank switching
+   circuit which is likely to cause system instability.  SBC
+   V2 does not have this issue.
+
+ZETA/ZETA2:
+ - Includes support for on-board floppy disk controller and
+   two attached floppy disks.
+ - Auto-detects ParPortProp and includes support for it if it
+   is attached.
+ - If ParPortProp is installed, initial console output is
+   determined by JP1.  If JP1 is shorted, console will go to
+   on-board serial port, if JP1 is open, console will go to
+   ParPortProp video and keyboard ports.
+
+N8:
+ - Includes support for on-board floppy disk controller and
+   two attached floppy disks.
+ - Includes support for on-board TMS9918 video and keyboard
+   including VT-100/ANSI terminal emulation.
+ - Includes support for on-board SD Card as hard disk and
+   assumes a production level N8 board (date code >= 2312).
+
+MK4:
+ - Includes support for on-board IDE port (CF Card via adapter).
+ - Includes support for on-board SD Card port.
+ - Auto-detects PropIO or PropIO V2 and installs associated
+   video, keyboard and SD Card support if present.
+ - Includes support for CVDU and VGA3 boards.  If detected at
+   startup, support for video and keyboard is installed
+   including VT-100/ANSI terminal emulation.

-Building a Custom ROM
----------------------
-
-At present, the build environment assumes you are running
-a current version of Microsoft Windows (either 32-bit or
-64-bit).
-
-If you are using Linux, David Giles has contributed a Linux
-makefile that should work for you.  Please read the
-LinuxBuild.txt file for more information.
-
-All required tools are included in the distribution.  You
-should not need anything other than what comes as part of
-Windows or as part of the distribution.
-
-In summary, the process involves the 4 steps below:
-
-  1) Create/update configuration file
-
-  2) Update/Add/Delete any files you want incorporated in
-     the ROM Disk
-
-  3) Run the build script (or makefile if you prefer) and
-     confirm there are no errors.
-
-  4) Burn the resultant ROM image and try it.
-
-The process is really very simple.  In fact, you can
-essentially skip steps 1 & 2 if you want to try simply
-building one of the existing configurations.
-
-Each of the 4 steps above is described in more detail
-below.
-
-1. Create/Update Configuration File
------------------------------------
-
-The settings for a build are primarily controled by
-a configuration file that is included in the build
-process.  In order to customize your settings, you
-need to modify an existing configuration file or
-create your own.
-
-If you look in the Source directory, you will see
-a series of files named config_xxxx_yyyy.asm.  Each of
-them corresponds to one of the standard configurations
-listed in the ROMList.txt file.
-
-You have two choices.  You can simply modify the existing
-configuration file that is closest to your situation, or
-you can copy it to a new config_xxxx_yyyy.asm file and modify
-that.  I recommend that you copy one to your own name so
-that you will always have the unmodified standard configuration
-files left in place.  So, for example, you could just
-copy config_ZETA_std.asm to config_ZETA_wayne.asm.  You MUST
-name your config file as config_xxxx_yyyy.asm.  The xxxx's
-must match your platform (N8VEM, ZETA, N8, S2I, or S100).
-The yyyy's can be whatever you want.
-
-The config files are simply text files with various
-settings.  Open your target config file with your
-favorite text editor and modify the settings as desired.
-
-Unfortunately, I have not yet documented each of the
-settings in detail; that will be a separate document
-provided in the future.  However, there are comments
-in the config file that will probably be sufficient
-for the most part.
-
-2. Update/Add/Delete ROM Disk Files
------------------------------------
-
-The files that are included on the ROM Disk of your
-ROM are copied from a set of directories during the
-build process.  This allows you to have complete
-flexibility over the files you want included in your
-ROM.
-
-If you look at the RomDsk directory, you will see
-a variety of subdirectories.  These subdirectories
-contain the files that will be included in the
-ROM disk.  The build process will determine
-which subdirectories to include files from based
-on the following rules:
-
-First, all files from either std_512 or std_1024 will
-be incuded depending on on the size of the ROM you
-are building.  If you are building a 512KB ROM, then
-all the files from std_512KB will be included.  If you
-are building a 1MB ROM, then all the files from std_1024KB
-will be included.  Essentialy, the files in std_1204KB are
-a superset of the ones in std_512KB because there is more
-space available for the ROM drive.
-
-Second, all files from the directory that corresponds to
-your configuration file will be included.  If you build
-the "ZETA_std" configuration, all files in cfg_ZETA_std will
-be added.  Note that these files will be in addition
-to the files from the std_XXXKB directory.
-
-If you created your own config file (like config_ZETA_wayne.asm
-described above), you MUST create a subdirectory within
-the RomDsk directory and populate it with the files
-you want added.  Normally, you would include the
-files from the original standard config.  So, if
-you created config_ZETA_wayne.asm from config_ZETA_std.asm,
-then you would create a subdirectory in RomDsk called
-cfg_ZETA_wayne and copy all the files from cfg_ZETA_std to
-cfg_ZETA_wayne.
-
-3. Run the Build Process
-------------------------
-
-NOTE: The process described here is the more commonly
-used build script.  If you wish to use a makefile
-instead, refer to the comments in the makefile in
-the Source directory as an alternative to the
-process described here.
-
-The build involves running commands at the command
-prompt.  From a Command Prompt window, you will need
-to change to the high level directory for the build.
-Normally, you would be changing to the RomWBW directory
-unless you renamed it.
-
-First, you will need to build the components that are
-common to all configurations.  These components do not
-require any configuration.  To build these, use the
-following commands and ensure that they complete
-without error:
-
-	BuildZCPR-DJ
-	BuildApps2
-
-To run the main build and be prompted for required information,
-just enter "Build".  You will be prompted for the information
-described below and the build should run.  If an error is
-encountered, the build should stop and display an error
-in red text.
-
-If you immediately receive the error "the execution of 
-scripts is disabled on this system", then you will need to 
-change the PowerShell Execution-Polcy to "RemoteSigned".
-To do this, you need to right-click on FixPowerShell.cmd and
-choose "Run as Administrator" to make the change.  If is
-critical that you right-click and use "Run as Administrator"
-or the change will not work (you will get an error
-indicating "Access to the registry denied" if you fail to
-use "Run as Administrator".
-
-The build script will prompt you for the following information
-which you will need to provide (don't worry, it is simple):
-
-Platform:
-
-Respond with the name of the platform that you are targeting.
-It must be one of N8VEM, ZETA, N8, S2I, or S100.
-
-Configuration:
-
-Respond with the name of the configuration you wish to build.
-A list of all available configurations is displayed for your
-convenience.  For example, if you are building the provided
-ZETA_std configuration, just enter "std".  If you have created a
-custom configuration as described above, you would enter
-"wayne".
-
-ROM Size [512|1024]:
-
-Respond with either "512" for a 512KB ROM build or "1024" for a
-1MB ROM build.  Only the two choices are possible at this time.
-It is important that you choose a ROM size that is no larger than
-the szie of the ROM you will ultimately be burning.  This is 
-dependant on your hardware.
-
-At this point, the build should run and you will see output related
-to the assembler runs and some utility invocations.  Just review
-the output for any obvioius errors.  Normally, all errors will
-cause the build to stop immediately and display an error message
-in red.
-
-You will see some lines in the output indicating the amount of
-space variouis components have taken.  You should check these
-to make sure you do not see any negative numbers which would
-indicate that you have included too many features/drivers for
-the available memory space.  Here are examples of the lines
-showing the space used:
-
-	DATA space remaining: 39 bytes.
-	BOOT LOADER space remaining: 3503 bytes.
-	CBIOS space remaining: 161 bytes.
-	DBGMON space remaining: 860 bytes.
-	ROMX space remaining: 8191 bytes.
-	BOOT LOADER space remaining: 3503 bytes.
-
-4. Deploy the ROM
------------------
-
-If you look in the Output directory.  You should find the following files:
-
-     <config>.rom - binary ROM image to burn to EEPROM
-     <config>.sys - system image that can be written to the start of a
-                    disk to enable boot from disk functionality
-     <config>.com - executable version of the system image that can be
-                    copied via xmodem to a running system to test
-                    the build.
-
-The actual ROM image is the file ending in .rom.  It should be exactly
-512KB or 1MB depending on the ROM size you chose.  Simply burn the .rom
-image to your ROM and install it in your hardware.
-
-Specifying Build Options on Command Line
-----------------------------------------
-
-If you don't want to be prompted for the options to the "Build"
-command, you can specify the options right on the command line.
-
-For example:
-
-	Build ZETA std 512
-
-In this case, you will not be prompted.  This is useful if you
-wish to automate your build process.

+Version 2.8.3, 2017-08-23
+https://www.retrobrewcomputers.org/
 
-Updated: 2014-09-19
-Version: 2.6.2
+RomWBW is a ROM-based implementation of CP/M-80 2.2 and Z-System for 
+all RetroBrew Computers Z80/Z180 hardware platforms including SBC 
+1/2, Zeta 1/2, N8, and Mark IV. Virtually all RetroBrew hardware is 
+supported including floppy, hard disk (IDE, CF Card, SD Card), Video, 
+and keyboard. VT-100 terminal emulation is built-in.
 
-This is an adaptation of CP/M-80 2.2 and ZSDOS/ZCPR
-targeting ROMs for all N8VEM Z80 hardware variations
-including SBC, Zeta, N8, and Mark IV.
+The RomWBW ROM loads and runs the built-in operating systems directly
+from the ROM and includes a selection of standard/useful applications
+accessed via a ROM disk drive.  A RAM disk drive is also provided
+to allow temporary file storage.
 
-NOTE: This is very much a work-in-progress.  It is
-severely lacking appropriate documentation.  I am 
-happy to answer questions and provide support though.
+Pre-built ROM images are included for all platforms.  Detailed system 
+customization is achieved by making simple modifications to a 
+configuration file and running a build script to generate a custom 
+ROM image. All source and build tools are included in the 
+distribution. As distributed, the build scripts run under any modern 
+32 or 64 bit version of Microsoft Windows.
 
-Acknowledgements
-----------------
+John Coffman's UNA hardware BIOS is fully supported by RomWBW. In the 
+case of UNA, a single ROM image (pre-built) is used for all supported 
+platforms and is customized using a ROM-based setup program. See the 
+UNA section below for more information.
 
-While I have heavily modified much of the code, I want
-to acknowledge that much of this is derived or
-copied from the work of others in the N8VEM
-project including Andrew Lynch, Dan Werner, Max Scane,
-David Giles, John Coffman, and probably many others 
-I am not clearly aware of (let me know if I omitted
-someone!).
+Quick Start
+-----------
 
-I especially want to credit Douglas Goodall for 
-contributing code, time, testing, and advice.  He created
-an entire suite of application programs to enhance the
-use of RomWBW.  However, he is looking for someone to
-continue the maintenance of these applications and
-they have become unusable due to changes within
-RomWBW.  As of RomWBW 2.6, these applications are
-no longer provided.
+A pre-built ROM image is included for each of the hardware platforms 
+supported. These ROM images are found in the Binary directory of the 
+distribution and have a file extension of ".rom". Simply program the 
+ROM of your system with the appropriate ROM image. Please see the 
+RomList.txt file in the Binary directory for details on selecting the 
+correct ROM image for your system and platform specific information.
 
-David Giles has contributed support for building the
-ROM under Linux and the CSIO support in the SD Card driver.
+Connect a serial terminal or computer with terminal emulation 
+software to the primary RS-232 port of your CPU board.  A null-modem 
+connection is generally required.  Set the line characteristics to 
+38400 baud, 8 data bits, 1 stop bit, no parity, and no flow control. 
+Select VT-100 terminal emulation.
 
-Usage Instructions
-------------------
+Upon power-up, your terminal should display a sign-on banner within 2 
+seconds followed by hardware inventory and discovery information.  
+When hardware initialization is completed, a boot loader prompt 
+allows you to choose a ROM-based operating system, system monitor, or 
+boot from a disk device.
 
-The distribution includes many pre-built ROM
-images in the Output directory.  The simplest way of
-using this ROM is to simply pick the pre-built ROM
-that most closely matches your preferences, burn it,
-and use it.
+CPU Speed
+---------
 
-Refer to the file called RomList.txt for a complete
-list of the ROMs that are included and the required
-hardware configuration that they support.
+RomWBW ROM images support virtually any CPU speed your system is
+running. However, there are some hardware-oriented caveats to be
+aware of.
+
+The use of high density floppy disks requires a CPU speed of 8 MHz or
+greater.
+
+The latest X-Modem file transfer programs (XM.COM, XM-A0.COM, and
+XM-A1.COM) require a CPU speeed of 6 MHz or greater to support the
+default RomWBW serial port speed of 38400 baud. Older variants of
+the X-Modem programs are included (XM5.COM, XM5-A0, and XM5-A1) which
+will handle 38400 baud on system running down to 4 MHz.
 
 Upgrading from Previous Versions
 --------------------------------
 
-Burn a new ROM image appropriate for your system
-and boot under that new ROM.  You may want to use
-a different ROM chip in case the new version does
-not work.
+Program a new ROM chip from an image in the new distribution. Install 
+the new ROM chip and boot your system. At the boot loader "Boot:" 
+prompt, select either CP/M or Z-System to load the OS from ROM.
 
-If you are using "boot from disk", you will need
-to update the OS image on all drives you boot from.
-To do this, use SYSCOPY.  Something like this
-would make sense:
+If you have spare rom chips for your system, it is always safest to
+keep your existing, work rom chip and program a new one so that you
+can return to the old one if the new one does not work properly.
 
-    B:SYSCOPY C:=B:ZSYS.SYS
+If you use a customized ROM image, it is recommended that you first
+try the pre-built ROM image first and then move on to generating a
+custom image.
 
-CPU Speed & Baud Rate
----------------------
+It is entirely possible to reprogram your system ROM using the FLASH
+utility from Will Sowerbutts on your ROM drive (B:). In this case,
+you would need to transfer the new ROM image to your system using
+X-Modem. Obviously, there is some risk to this approach since any
+issues with the programming or ROM image could result in a
+non-functional system.
 
-The startup serial port baud rate in all pre-built
-RomWBW variants is 38.4Kbps.  While this speed is
-nice in that it provides great display and file
-transfer performance, it does push the limits of
-slower hardware.  Specifically, XModem v12.5 (the
-default XM.COM) on the distribution is unable to
-service the serial port fast enough if the CPU is
-running at 4MHz.  Your options are to 1) use the
-old version of XModem (XM5.COM), put a faster CPU
-oscillator in your system (6MHz or above), or
-3) decrease the baud rate by building a custom
-ROM.
+If your system has any bootable drives, then update the OS image on
+each drive using SYSCOPY. For example, if C: is a bootable drive
+with the Z-System OS, you would update the OS image on this drive
+with the command:
 
-UNA Variant
------------
+    B>SYSCOPY C:=B:ZSYS.SYS
 
-RomWBW will now run under it's native BIOS (HBIOS) or
-under UNA BIOS (UBIOS).  There are pre-built ROM
-images for UNA in the Output directory.
+If you have copies of any of the system utilities on drives other
+than the ROM disk drive, you need to copy the latest version of the
+programs from the ROM drive (B:) to any drives containing these
+programs. For example, if you have a copy of the ASSIGN.COM program
+on C:, you would update it from the new ROM using the COPY command:
 
-CP/M vs. ZSystem
-----------------
+    B>COPY B:ASSIGN.COM C:
 
-There are two OS variants included in this distribution
-and you may choose which one you prefer to use.
+The following programs are maintained with the ROM images and all
+copies of these programs should be updated when upgrading to a new
+ROM version:
 
-The traditional Digital Research (DRI) CP/M code is the first
-choice.  The Doc
-directory contains a manual for CP/M usage (cpm22-m.pdf).
-If you are new to the N8VEM systems, I would currently
-recommend using the CP/M variant to start with simply
-because they have gone through more testing and you
-are less likely to encounter problems.
+    - ASSIGN.COM
+    - FORMAT.COM
+    - OSLDR.COM
+    - SYSCOPY.COM
+    - TALK.COM
+    - FD.COM
+    - XM*.COM
 
-The other choice is to use the most popular non-DRI
-CP/M "clone" which is generally referred to as
-ZSystem.  These are intended to be
-functionally equivalent to CP/M and should run all
-CP/M 2.2 code.  They are optimized for the Z80 CPU
-(as opposed to 8080 for CP/M) and have some potentially
-useful improvements.  Please refer to the Doc directory
-and look at the files for zsdos and zcpr (zsdos.pdf &
-zcpr.doc as well as ZSystem.txt).
+UNA Hardware BIOS
+-----------------
 
-Both variants are now included in the pre-built ROM images.
-You will be given the choice to boot either CP/M or
-ZSystem at startup.
+John Coffman has produced a new generation of hardware BIOS called 
+UNA. In addition to the classic ROM images, RomWBW comes with a 
+UNA-based image that combines the UNA BIOS with the RomWBW OS 
+implementations and applications.
 
-Building a Custom ROM
----------------------
+UNA is customized dynamically using a ROM based setup routine and the
+setup is persisted in the system NVRAM of the RTC chip. This means
+that a single UNA-based ROM image can be used on most of the
+RetroBrew platforms and is easily customized. UNA also supports FAT
+file system access that can be used for in-situ ROM programming and
+loading system images.
 
-I strongly suggest you start with burning one of the
-pre-built ROMs and making sure that works first.  Once
-you have gotten past that hurdle, you should consider
-building a custom ROM.  It is very easy and the
-distribution comes with everything that is needed to
-run a build on a Windows 32 bit or 64 bit system --
-basically Windows XP or above.  There is also a
-Linux build now available.
+While John is likely to enhance UNA over time, there are currently a
+few things that UNA does not support:
 
-Creating a custom ROM allows you to customize a lot
-of useful stuff like adding support for a DSKY if
-you have one.
+    - Floppy Drives
+    - Video/Keyboard/Terminal Emulation
+    - Zeta 1 and N8 Systems
+    - Some older support boards
 
-Please refer to the Build.txt file in the Doc directory
-for detailed instructions for building a custom ROM.  If
-you are using Linux, also read the LinuxBuild.txt file.
+If you wish to try the UNA variant of RomWBW, then just program your
+ROM with the ROM image called "UNA_std.rom" in the Binary directory.
+This one image is suitable on all of the platforms and hardware UNA
+supports.
 
-Formatting Media
-----------------
+Please refer to the RetroBrew Computers Wiki for more information on
+UNA.
 
-<TBD>
+CP/M vs. Z-System
+-----------------
 
-Creating Bootable Media
+There are two OS variants included in this distribution and you may
+choose which one you prefer to use. Both variants are now included
+in the pre-built ROM images. You will be given the choice to boot
+either CP/M or Z-System at startup.
+
+The traditional Digital Research (DRI) CP/M OS is the first choice.
+The Doc directory contains a manual for CP/M usage ("CPM
+Manual.pdf"). If you are new to the RetroBrew Computer systems, I
+would currently recommend using the CP/M variant to start with simply
+because it has gone through more testing and you are less likely to
+encounter problems.
+
+The other choice is to use the most popular non-DRI CP/M "clone"
+which is generally referred to as Z-System. It is intended to be
+functionally equivalent to CP/M and should run all CP/M 2.2 code. It
+is optimized for the Z80 CPU (as opposed to 8080 for CP/M) and has
+some potentially useful improvements. Please refer to "ZSDOS
+Manual.pdf" and "ZCPR Manual.pdf" in the Doc directory for more
+information on Z-System usage.
+
+ROM Customization
+-----------------
+
+The pre-built ROM images are configured for the basic capabilities of
+each platform. If you add board(s) to your system, you will need to
+customize your ROM image to include support for the added board(s).
+
+Essentially, the creation of a custom ROM is accomplished by updating
+a small configuration file, then running a script to compile the
+software and generate the custom ROM image. At this time, the build
+process runs on Windows 32 or 64 bit versions. All tools (compilers,
+assemblers, etc.) are included in the distribution, so it is not
+necessary to setup a build environment on your computer.
+
+For those who are interested in more than basic system customization, 
+note that all source code is included (including the operating 
+systems).
+
+Note that the ROM customization process does not apply to UNA. All
+UNA customization is performed within the ROM setup script.
+
+Complete documentation of the customization process is found in the
+ReadMe.txt file in the Source directory.
+
+Source Code Respository
 -----------------------

+All source code and distributions are maintained on GitHub at
+"https://github.com/wwarthen/RomWBW".  Code contributions are very
+welcome.
 
-Using Slices on Mass Storage Devices
-------------------------------------
+Distribution Directory Layout
+-----------------------------
 
-<TBD>
+The RomWBW distribution is a compressed zip archive file organized in 
+a set of directories.  Each of these directories has it's own
+ReadMe.txt file describing the contents in detail.  In summary, these
+directories are:
 
-Managing Console I/O
---------------------
+  Binary: The final output files of the build process are placed
+          here.  Most importantly, are the ROM images with the
+	  file names ending in ".rom".
 
-<TBD>
+  Doc:    Contains various detailed documentation including the
+          operating systems, RomWBW architecture, etc.
 
-Notes
+  Source: Contains the source code files used to build the software
+          and ROM images.
+  
+  Tools:  Contains the MS Windows programs that are used by the
+          build process or that may be useful in setting up your
+	  system.

+Acknowledgements
+----------------
+
+While I have heavily modified much of the code, I want to acknowledge
+that much of the work is derived or copied from the work of others in
+the RetroBrew Computers project including Andrew Lynch, Dan Werner,
+Max Scane, David Giles, John Coffman, and probably many others I am
+not clearly aware of (let me know if I omitted someone!).
+
+I especially want to credit Douglas Goodall for contributing code,
+time, testing, and advice. He created an entire suite of application
+programs to enhance the use of RomWBW. However, he is looking for
+someone to continue the maintenance of these applications and they
+have become unusable due to changes within RomWBW. As of RomWBW 2.6,
+these applications are no longer provided.
+
+David Giles has contributed support for the CSIO support in the SD
+Card driver.
+
+The UNA BIOS is a product of John Coffman.
