+%description
+withlock is a locking wrapper script to make sure that some program
+isn't run more than once. It is ideal to prevent periodic jobs spawned
+by cron from stacking up.
+
+The locks created are valid only while the wrapper is running, and
+thus will never require additional cleanup, even after a reboot. This
+makes the wrapper safe and easy to use, and much better than
+implementing half-hearted locking within scripts.
