<para>The CentOS Artwork Repository is supported by <ulink
url="http://subversion.tigris.org/">Subversion</ulink>, a version
control system which allows you to keep old versions of files and
directories (usually source code), keep a log of who, when, and
why changes occurred, etc., like CVS, RCS or SCCS.</para>
<para>When using Subversion there is one "source repository" and
many "working copies" of that source repository. The working
copies are independent one another, can be distributed all around
the world and provide a local place for designers, documentors,
translators and programmers to perform their works in a
descentralized way. The source repository, on the other hand,
provides a central place for all independent working copies to
interchange data and provides the information required to permit
extracting previous versions of files at any time.</para>
