+name:                hsbackup
+version:             0.1
+synopsis:            simple utility for rolling filesystem backups
+description:         Take backups of a directory and store them in a hashed format.
+                     Currently only supports plain files and directories. Very crude
+                     and limited, do NOT use in production. To be improved. Will break
+                     backward compatibility in future versions.
