Subversion!
I finally decided to try out subversion. Naturally, I would only want to do that if I could use it from eclipse. I saw that the subclipse plugin was supposed to work on OSX, so I gave it a try.
I first downloaded the Metissian Subversion 1.1 package. I then installed subclipse for Eclipse 3.0.
I installed subversion 1.1 on an old Solaris box and bingo!
I used cvs2svn to convert part of our repository. It worked great.
The subclipse integration is awesome. It works just like CVS in eclipse. I'l going to play with it for a bit longer, but I'm ready to switch to subversion!
