subversion 1.6.6dfsg-2ubuntu1 (amd64 binary) in ubuntu lucid

 Subversion, also known as svn, is a version control system much like
 the Concurrent Versions System (CVS). Version control systems allow
 many individuals (who may be distributed geographically) to
 collaborate on a set of files (typically source code). Subversion has
 all the major features of CVS, plus certain new features that CVS
 users often wish they had.
 .
 This package includes the Subversion client (svn), tools to create a
 Subversion repository (svnadmin) and to make a repository available
 over a network (svnserve).
