Versioning / Change control

[mr_vodka]

This topic doesnt really belong anywhere so I guess I will post it here.

I wanted some feedback on what some of you guys use for versioning, version control, change control, or whatever you wanna call it. I am going to look into some products and I was thinking about possibly open source. Have you gusys had any experience with some of these products? Plus/Minuses?

On the unix side, we used to use sccs but I am not sure what would be the best for FileMaker files. We are in the midst of hiring multiple developers so I do not want my team members to overwrite each other'w work; thus the need for versioning.

I've used zillions (ok four) version control apps; CVS is good on the unix side and has a a windows app called wincvs that works quite well

Are you in a mixed environment?
