 Alternately, you can hack the 'cvsweb' package to call CvsGraph. There are  
 several scripts and patches available from the CvsGraph homepage (see below for  
 address). However, the scripts are no longer maintained because ViewCVS has  
 native support now.

125    - contrib/automatic_documentation:
126      If you are interested in tag-management with respect to the correct branch
127      information, then I suggest that you take a look at the contribution from
128      Henrik Carlqvist. He submitted some server-side scripts that can manage tags
129      in a better fashion than cvs on its own.
