Some ports require a particular user account to be present,
      usually for daemons that run as that user.  For these ports,
      choose a unique UID from 50 to 999 and
      register it in ports/UIDs (for users) and
      ports/GIDs (for groups).  The unique
      identification should be the same for users and groups.
Please include a patch against these two files when requiring a new user or group to be created for the port.
Then use USERS and
      GROUPS in
      Makefile, and the user will be
      automatically created when installing the port.
USERS= pulse GROUPS= pulse pulse-access pulse-rt
The current list of reserved UIDs and GIDs can be found
      in ports/UIDs and
      ports/GIDs.
