(HAMMER VERSION 3+) Remove a snapshot given its softlink or transaction id. If specifying a transaction id the snapshot is removed from file system meta-data but you are responsible for removing any related softlinks. If a softlink path is specified the filesystem and transaction id is derived from the contents of the softlink. If just a transac- tion id is specified it is assumed to be a snapshot in the HAMMER filesystem you are currently chdir'd into. You can also specify the filesystem and transaction id explicitly.
