# To run e.g. 15 instances of this client, run this command inside screen:
# for i in `seq 1 15`; do screen ./example.pl; done
# AGENTID may be prefixed with + to indicate newly bred agent.
#
# GENDER may be 0 for no breeding, 1 for "male" (active) or 2 for
# "female" (passive); default is 0; breeding requires the script
# to be run in screen.
#
# To run e.g. 20 instances of this client with breeding enabled,
# start screen and from within run:
# for i in `seq 1 10`; do screen ./example.pl 27753 0 1; screen ./example.pl 27753 0 2; done
