Re: Use of CVS on large scales

With the possible exception of mySQL, those are all excellent examples of
"great" software packages that are version controlled with CVS.

I used to work in the Video division (which is now Grass Valley Group) of
Tektronix, and until about a year ago, they used CVS for all of their
revision control needs.  They recently moved to ClearCase, and I believe
their reasons for switching were managerial, not technical.  Apparently they
liked the idea of being able to generate reports from ClearCase and were
wooed by some of the other bells and whistles ClearCase offered.

When Tektronix used CVS, it was sufficient for many very large projects,
each with multiple branches, and there were never any mishaps (in my over 4
years of working there) or loss of data because of CVS itself.  The only
possible problem area you might find is CVS's lack of support for binary
files, but even that can be managed reasonably with careful use.

I have since implemented CVS twice: once for an internet software
development company (who had NO version control at the time), and then again
for my current job as one of several sub-contractors, geographically
separated, all working on the same project.  It is working very well (with
the exception that the server's disk controller is bad), and after the
initial setup, I am now able to easily manage it myself with very little
time or effort.

In my opinion, CVS works GREAT, and I would HIGHLY recommend it for ANY size
project - large or small.
