Newbie question, versioning configuration files

Howdy,

I want to put some configuration files under
version control.

All the descriptions of CVS usage I've seen
keep working copies of files together, somewhere
like ~/cvs/config

I'd like a recipe which keeps the copy of a file
in the CVS working directory in synch with the
"real" file.

IE: /etc/profile has a copy in ~/cvs/config/profile.
When I do
# cvs commit
in  /cvs/config, I want the recipe to check
if /etc/profile is newer than ~/cvs/config/profile,
and update the versioned copy before commiting to cvs.

In reading the doc it seems that there are a number
of ways this could be done...

Please point me in the right direction.

Thanks,
Kent
