Well, you are able, it's just a mission. You can use the CVSWeb
interface to find out what's changed on a file. 

I assume you're talking about people who use CVSup to fetch the latest
sources? The attached shell script can be used by CVSup users to find
out what was changed in the "deltas" shown in CVSup output. With a
little massaging, it could easily be taught to fetch _all_ diffs on _any
file changed during a CVSup run.

Ciao,
Sheldon.
