Remote sshd command checker for ZFS Snapshot Daemon

 ZFS Snapshot Daemon is written in python, and it can remotely manage ZFS
 snapshotting and backup from a central back up server. This is the
 security plugin command for sshd that implements ForceCommand functionality,
 or the command functionality in the .ssh/authorized_keys file (See
 the sshd_config(8) and sshd(8) man pages respectively).
 .
 It executes commands from the SSH_ORIGINAL_COMMAND variable after checking
 them against a list of configured regular expressions.
