#HA-Proxy version 1.4.18 2011/09/16
#Copyright 2000-2011 Willy Tarreau <w@1wt.eu>
#
#Usage : haproxy [-f <cfgfile>]* [ -vdVD ] [ -n <maxconn> ] [ -N <maxpconn> ]
# [ -p <pidfile> ] [ -m <max megs> ]
# -v displays version ; -vv shows known build options.
# -d enters debug mode ; -db only disables background mode.
# -V enters verbose mode (disables quiet mode)
# -D goes daemon
# -q quiet mode : don't display messages
# -c check mode : only check config files and exit
# -n sets the maximum total # of connections (2000)
# -m limits the usable amount of memory (in MB)
# -N sets the default, per-proxy maximum # of connections (2000)
# -p writes pids of all children to this file
# -de disables epoll() usage even when available
# -ds disables speculative epoll() usage even when available
# -dp disables poll() usage even when available
# -sf/-st [pid ]* finishes/terminates old pids. Must be last arguments.
