==== About Subversion ====
From [http://http://en.wikipedia.org/wiki/Subversion_(software) Wikipedia]:

  '''Subversion''' ('''SVN''') is a [http://en.wikipedia.org/wiki/Revision_control version control] system initiated in 2000 by [http://en.wikipedia.org/wiki/CollabNet CollabNet] Inc. It is used to maintain current and historical versions of files such as [http://en.wikipedia.org/wiki/Source_code source code], web pages, and documentation. Its goal is to be a mostly-compatible successor to the widely used [http://en.wikipedia.org/wiki/Concurrent_Versions_System Concurrent Versions System] (CVS).

  Subversion is well-known in the open source community and is used on many open source projects, including [http://en.wikipedia.org/wiki/Apache_Software_Foundation Apache Software Foundation], [http://en.wikipedia.org/wiki/KDE KDE], [http://en.wikipedia.org/wiki/GNOME GNOME], [http://en.wikipedia.org/wiki/Free_Pascal Free Pascal], [http://en.wikipedia.org/wiki/FreeBSD FreeBSD], [http://en.wikipedia.org/wiki/GNU_Compiler_Collection GCC], [http://en.wikipedia.org/wiki/Python_(programming_language) Python], [http://en.wikipedia.org/wiki/Django_(web_framework) Django],[http://en.wikipedia.org/wiki/Ruby_(programming_language) Ruby], [http://en.wikipedia.org/wiki/Mono_(software) Mono], [http://en.wikipedia.org/wiki/SourceForge.net SourceForge.net], [http://en.wikipedia.org/wiki/ExtJS ExtJS] and [http://en.wikipedia.org/wiki/Tigris.org Tigris.org]. [http://en.wikipedia.org/wiki/Google_Code Google Code] also provides Subversion hosting for their open source projects. [http://en.wikipedia.org/wiki/BountySource BountySource] systems use it exclusively. [http://en.wikipedia.org/wiki/Codeplex Codeplex] offers access to both subversion as well as other types of clients.

  Subversion is also being adopted in the corporate world. In a 2007 report by [http://en.wikipedia.org/wiki/Forrester_Research Forrester Research], Subversion was recognized as the sole leader in the Standalone Software Configuration Management (SCM) category and a strong performer in the Software Configuration and Change Management (SCCM) category.^[http://en.wikipedia.org/wiki/Subversion_(software)#cite_note-0 "[1]"]^

  Subversion is released under the [http://en.wikipedia.org/wiki/Apache_License Apache License], making it [http://en.wikipedia.org/wiki/Free_software free software].
