+This is the SVN root of the RomWBW project.
+
+The standard SVN subdirectores exist including
+trunk, branches, and tags.
+
+The most recent released version of the project
+is available at /tags/Release.  Unless you have
+a good reason to believe otherwise, you should
+use that location to retrieve files.
+
+The "work in progress" is maintained in /trunk.
+Feel free to take a look, but expect it to
+contain stuff that is not fully baked and it
+may not even build properly.
