    <para>The CentOS Artwork Repository is supported by 

    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 work 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>
