-* CHECK_OVERCR.C
-*
-* Program: Over-CR collector plugin for Nagios
-* License: GPL
-* Copyright (c) 1999 Ethan Galstad (nagios@nagios.org)
-*
-* $Id$
-*
-* Description:
-*
-* Notes:
-* - This plugin requires that Eric Molitors' Over-CR collector daemon
-* be running on any UNIX boxes you want to monitor. Over-CR
-* is available from * http://www.molitor.org/overcr/
-*
-* Modifications:
-*
-* 08-11-999 Jacob Lundqvist <jaclu@grm.se>
-* Load was presented as a one digit percentage - changed to two digit
-* value * before load of 11.2 was presented as "1.2%" (not very
-* high). Warning and Critical params were int's, not very good
-* for load, changed to doubles, so we can trap loadlimits like
-* 1.5. Also added more informative LOAD error messages.
