markup for translation, move send_buffer assignment to process_args so process_tcp_request can be moved outside the conditional, replace if/esleif with switch, replace #defines with enum

/******************************************************************************
*
* 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.
