"$Name: turn NNTP service on or off.
$Usage
$Name turns NNTP service on or off by creating or removing a status file
read by nntpd, $StatusFile.  If $StatusFile exists, nntpd returns an NNTP
status message indicating that the news server is shut down (note, this
requires a modified nntpd or a front end for nntpd).
Options:
on:  Turn on NNTP service by removing the status file.
off: Turn off NNTP service and report how many NNTP connections are currently
     active.  These nntpd processes are not killed.
If $Name is invoked without arguments, it tells whether NNTP service is on or
off."
