If you are working on a team where multiple people need to edit the same files you generally need some kind of version control software. A few popular version control systems are Perforce($700 per user), Alien Brain ($1200 per user) and Subversion (free). mayasvn is a start at integrating subversion into maya so using subversion as your version control system becomes extremely easy
Usage is straight forward. Once installed if you attempt to open a maya file that is under subversion control you will be asked if you want to get a lock on the file. If you answer yes mayasvn will attempt to lock the file. If you answer no or if you choose not to lock the file you will be warned that you are not allowed to edit the file.
When saving mayasvn will check if the file you are saving is under subversion control. If it is you will be asked if you want to commit the file. If it is not, mayasvn will check if the folder you are saving to is under subversion control. If so you will be asked of you want to add the file to subversion. In either case if you answer yes you are given the option to enter a comment and to then to optionally get the lock again if you want to continue to edit the file.
