# INFORMATION TOOL ABOUT THE # OF ONLINE PLAYERS ON ATHENA SERVERS
#
# By connection on the athena login-server, this software displays the
# number of online players.
#
#-------------------------------------------------------------------------
# Software usage:
# Configure the IP, the port and a valid account of the server.
# After, use at your choice:
# ./getlogincount.pl - display the number of online players on all servers.
# ./getlogincount.pl --premier or
# ./getlogincount.pl --first -- display the number of online players of the
# first server in the received list.
# ./getlogincount.pl [servername] -- display the number of online players
# of the specified server.
#
# If successfull, the software return the value 0.
