Sounds like a good one!
I don't use cvs or svn much for day-to-day stuff beyond storing some
configs in there (unix hosts and routers). However, I did recently do
some work moving a client from cvs to subversion, and it's still somewhat
fresh in my mind. Two things that I think are essential if you've got a
background in cvs:
That section of the (excellent) free, online svn book is a really good
read. While svn and cvs try to present the user with similar/compatible
tools, the way things work behind the scenes are radically different.
That section helps explain how and things didn't click for me until I read
that. The folks actually using svn were not quite understanding why a
change in one file bumped the revision number on every file in the
One also needs to understand that branches and tags are much more
loose/arbitrary than in cvs and are more of a "virtual" grouping of files
than they are in cvs.
Since many folks are not starting from scratch, but moving from cvs to
svn, that tool is very cool. It gets quite hairy if your cvs repo is kind
of a mess, but it tries really hard to get things right.
I'll also add a third, which is more of a question... With cvs, it's easy
to set an environment variable in your shell to tell cvs where the repo
lives. There is no such thing in svn. What kind of hackery is out there
for those that don't like typing svn urls with every command?
