I use git for my work projects, and I have use many other code control
programs. But, they are NOT versioning in the sense of VMS. For instance
in git (and other code management systems) you must explicitly check in
your changes (such as git commit). With a versioning file system,
everytime you save a file a backup version is kept up to the limit set
by the system (or you). Let's say I am working on a piece of code, and I
save it, but don't check it in, then the next day, I really screw
something up in that file, but I have saved it. If I want to recover
from git (or svn, or cvs, ...) I've lost some of my changes. With a VMS
style of versioning, every time I save the file I get a new version.
