[xymon] External scripts for Xymon client on Xymon Server

[Ralph Mitchell]

You probably have a log file somewhere.  In Tim's example, it defined like
this:

         LOGFILE $HOBBITCLIENTHOME/logs/na2.log

If the log doesn't show anything interesting, you should be able to *make*
it show something interesting.  For example, a "set -x" at the top of the
script will show you exactly what it does.

You can also execute the script manually as if it were Xymon executing it,
using the bbcmd command.
