the output of procps v3.3 (the changelog refers to it as modernizing it), it's
output changed and breaks the the check_memory script as shipped with many linux
distributions. This version supports both the old and the new format so that
is indifferent of which version of procps (to date) is used. No other changes
were made to the script.

cgi-bin/nagiosstatus.sh
-----------------------
Very simplistic CGI-BIN script that checkes whether nagios is still running and
still updating its status. It wil always return an HTTP Status 200 (OK) and a
simple text page with one of the following texts:
- STOPPED - in case the nagios process is not running
- STALLED - in case the nagios status file has not been updated for 5 minutes
- OK - when Nagios is running and updated its status file < 5 minutes ago
I wrote this script to be used with an external monitoring system, I use it with
the free subscription from [Pingdom](http://www.pingdom.com) to get alerts when
my Nagios monitoring system is no longer reachable.
