Advanced version control system

 Apache Subversion, also known as svn, is a centralised version control
 system. Version control systems allow many individuals (who may be
 distributed geographically) to collaborate on a set of files (source
 code, websites, etc). Subversion began with a CVS paradigm and
 supports all the major features of CVS, but has evolved to support
 many features that CVS users often wish they had.

 This package includes the Subversion client (svn, svnsync), repository
 administration tools (svnadmin, svnlook) and a network server (svnserve).
