This allows you to access +the contents of individual files in the repository and also to look at the revision +history and commit logs of individual files.

This gives you much more control over what you can +do with the repository and allows you to checkout whole source trees +and keep them up-to-date via normal CVS commands. This is the +preferred method of access if you are a developer and not +just a casual browser. +</para> + +<para> +To download the latest CVS source code, point your +browser at the URL : +<ulink noescape="1" url="http://www.cyclic.com/">http://www.cyclic.com/</ulink>. +and click on the <quote>How to get CVS</quote> link. CVS is free software under +the GNU GPL (as is Samba). Note that there are several graphical CVS clients +that provide a graphical interface to the sometimes mundane CVS commands. +Links to theses clients are also available from the Cyclic Web site. +</para> + +<para> +To gain access via anonymous CVS, use the following steps. +For this example it is assumed that you want a copy of the +Samba source code.
