   pu[rge]

   Purges expired local registry entries.

   This command has no options or arguments.

   The time limit, or lifespan, for which an entry in the local
   registry is valid is set as a property of the local registry
   with the properties subcommand.  When the purge subcommand is
   run, it deletes all expired entries.  The lifespan begins when
   an entry for the principal is added to the local registry (that
   is, the beginning of the lifespan is the last time the principal
   logged in to the local machine.) The lifespan ends after the time
   limit set as a local registry property.
