Usage $PROG_NAME:

   -a			Enable/disable for all users (general.cfg)
   -i			Scalix instance name.
   -r			Remove (disable) logging instead of enabling.
   -X			With '-a -r' also recursively remove logging for individual users (users.cfg).
Examples:
   $PROG_NAME -u "User Person"
   $PROG_NAME -u "User Person" -r
   $PROG_NAME -a
   $PROG_NAME -a -r -X
