I wanted to know if any one else is writing a BTRFS gui other than the writers of BTRFS-GUI (http://carfax.org.uk/btrfs-gui) who haven't updated svn sense 2009 I think. Is there any documentation on communicating with /dev/btrfs-controle ? a command list? I've looked at the source of btrfs.c but I don't want to depend on my understanding of it.
