# Title :     hobbit-games
# Author :    Damien Martins  ( doctor |at| makelofine |dot| org)
# Date :      2008-11-20
# Purpose :   Check game server status
# Platforms : Uni* (having quakestat/qstat binary)
# Tested :    Hobbit 4.2.0-Xymon 4.2.2 / QStat (QuakeStat) 2.11-1 (Debian Etch Package)
#
# History:
#	0.1   20 nov 2008 Damien Martins
#               - first tests /trying to get status and report to hobbit server (with Warsow game)
#	0.2   14 jan 2009 Damien Martins
#		- Adding support for all games supported by QuakeStat
#		- Changing script output to get graphs on Xymon server
#		- Discovering RRD conf in Xymon, to get graphs from this script's output.
#		- Changing configuration file syntax according to multi-game support
#	0.3   11 feb 2009 Damien Martins
#		- Changing output to get NB_PLAYERS value linked to server's name instead of server IP:PORT, in order to get readable graphs infos.

# Special thanks to Imhotep (imhotep@heliopolis.se) for creating a suite for generating RRD graphs for game servers activity. His works inspired all this script (but he doesn't know it nor me I presume).

# DEBUG :
# TO TEST, JUST USE : (to know what game to use, consult hobbit-games.list)
