Chiron FS - A FUSE based replication filesystem

Chiron FS is a FUSE based filesystem which implements replication at the FILESYSTEM LEVEL like RAID 1 does at the DEVICE LEVEL.

The replicated filesystems may be of any kind you want the only requisite is that you mount it.

No need for special configuration files, the setup is as simple as one mount command (or one line in fstab).
