#2 Script should be able to read from existing cvs log file.

[Matt Bateman]

I use the cvsplot tool in conjunction with other tools
for reporting on a cvs repository. Most tools need cvs
log output to work on. It would save a lot of time if
the cvsplot script could use cvs log output that has
already been generated. This way, cvs log data
wouldn't have to be generated for each tool.

Great script!
