If you create a loginfo script instead (or rather as an extra item)
and let this record what has been committed into a logfile of some
kind, then you could let the postcommit script read this and determine
if you need to update the site and also which files are involved.
The loginfo call will surely finish before the postcommit call is made
so there is no race between them either.
Your logic as to what to do can reside in the postcommit script and
the loginfo supplies the info to act on.
You can use the $CVSPID variable to get at the cvs process running the
commit so you can read the correct info in the postcommit file (but
you have to expande the PID a bit and get extra info to make the
identifier unique, like I had to in my mailing program).
