   y-coordinates in the imagemap when generated upside down.

27    - The timezone variable does not seem to exist on Mac OSX. I have no clue how
28      to patch this yet.
29      Anyhow, the timezone problem is much worse, because it needs to be calculated
30      from the revision's commit-time and not the current timezone (Daylight saving
31      must be accounted for at commit's time, not current).

 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 However, the scripts are no longer maintained because ViewCVS has  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.
