+-- | Sets the url to use as the origin of propellor's git repository.
+--
+-- When propellor --spin is used to update a host, the url is taken from
+-- the repository that --spin is run in, and passed to the host. So, you
+-- don't need to specifiy this property then. 
+--
+-- This property is useful when hosts are being updated without using
+-- --spin, eg when using the `Propellor.Property.Cron.runPropellor` cron job.
