The single most important aspect of version control is philosophy.  There is
obviously a reason version control has been endorsed in a particular case
        -everybody does it
        -we need 'backups'
        -we would like to track changes and return to old code that worked
when everything breaks
        -we need to have multiple users work on the same code at the same

If you don't know why you want it, you can't make it solve your problems.  I
recommend really focusing on the needs because they vary significantly
depending on the makeup of the developers and the company.  I have worked
with a large outfit that used the extremely expensive commercial product
"Rational Clearcase" and almost never had a successful build due to people
committing/checking-in code that wasn't working.  Perhaps that was not one
of their goals for version control, but most large groups would say that it
is.  So hopefully I make my point that philosophy is most important - there
is not always a "correct" way to use a tool - nothing in any version system
stops you from checking in non-functional code, but if you always want the
main branch to be buildable you could make that one of your behavioral rules
for the system.

Regardless of your choice in a particular tool, I do recommend reading the
SVN manual if you are new to version control - they seem to spend lots of
time on philosophy, so you can jumpstart your abilities on any platform.

On another note, I have heard from a reliable source that "cvsnt" has fixed
alot of the problems (philosophic/ functionality?) with regular cvs, I've
certainly found the developers very responsive to bug fixes & enhancements.
Not having used anything else, I couldn't mention specifics.
