This utility will use the information supplied in your manpath
configuration file to determine which cat directories you require.  It
will then create them as the supplied <owner> and <group> and with
access permissions of <mode>.  <mode> can be any mode accepted by chmod.

A mode of 0755 is recommended in most cases.

The man-db package must be _installed_ for this script to work.
