 Subversion 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.
 .
 These modules are required to interface with Subversion from Ruby 1.8.
 This would be useful if you wanted to, for example, write a Ruby
 script that manipulates a subversion repository or working copy.
