How do you manage code changes?

I'm curious about experiences with the use of source code repositories (CVS, RCS, DARCS,...) and if anyone has been able to incorporate them into their teams development process.

We've tried but the use of a central repository has not worked well due to the fact that our development is on machines that are not regularly networked together. We archive the best code of the day and use it to seed a development directory for the next day's work.

What we have done that has worked fairly well, is use a contextual diff tool (KDIFF3) that provides a quick way to compare and merge two source directories. Using this tool, we can quickly see what has changed from a previous day's work, or we can merge separate development directories into one.
