My original problem is that I have a directory where I write various scripts. Each of them is independent of others, and usually one-file-long. I want to have some versioning ap
I can only think of these two lightweight versioning systems:
1) Using Dropbox with the Pack-Rat upgrade, to keep a full history of versions for each file automatically backed up and with the possibility to be shared with multiple Dropbox users: https://www.dropbox.com/help/113
If you have multiple machines managed by the same user (you), the synching would be automatic. Also if the machines are in the same LAN, Dropbox is smart enough to sync the files over the local network, so big files shouldn't be a worry.
2) Using a 'Versions' aware text editor for Mac OS X Lion. I'd expect TextMate, Coda and other popular Mac code editors to be updated to support this feature when Lion is released.
