-## Watch the state of the system relative to the news subsystem.
-## As controlled by the control file, when space or inodes are almost
-## exhausted innd is throttled, or paused, similarly if the load is
-## too high - when conditions revert to normal, innd is restarted.
-## No logging is done here, watch for syslog reports from innd.
-## Written by Mike Cooper <mcooper@usc.edu>.
-## Extensively modified by <kre@munnari.oz.au>.
-## Watch a log file and send mail when it gets new output by
-## Steve Groom <stevo@elroy.Jpl.Nasa.Gov>
-## Steve's extensions merged in innwatch by
