This Java based cvs GUI looks promising. I've always had the dangest time cracking the cvs nut for some reason. Visual SourceSafe, Microsoft's revision control system, on the other hand, I learned without a manual in about 10 minutes. Hopefully this app will bridge ye olde "Mac user mentality; I just want to click one button" gap I've got on cvs for whatever reason.

Also might be interesting to point out this app is based on the Netbeans Java cvs module. Open source and open licenses strike again!
