CopyFS aims to solve a common problem. Given a directory full of configuration files or other important files that can be modified, it ensures that a backup of a file will be made before modifying it. This filesystem is based on FUSE for Linux, and makes the whole process transparent, automatically keeping versioned copies of all the changes done to a file under its control.
is this really GPL ?
looking at version 0.7.1 I can't find any license information. Is this really GPL software ?
