# Note about ulimits:
# if you want to set ulimits, e.g. to increase the max number of open file handle,
# or to allow core files, you can do so by editing /etc/sysconfig/apache2 and
# simply write the ulimit commands into that file.
# Example:
# ulimit -n 16384
# ulimit -H -n 16384
# ulimit -c unlimited
# See the output of "help ulimit" in the bash, or "man 1 ulimit".

Usage: $0 <command> <server flags>
where <command> is one of:
start - start httpd
startssl - start httpd with -DSSL
stop - stop httpd (sending SIGTERM to parent)
try-restart - stop httpd and if this succeeds (i.e. if
it was running before), start it again.
status - check whether httpd is running
restart - stop httpd if running; start httpd
restart-graceful - stop httpd gracefully if running; start httpd
reload|graceful - do a graceful restart by sending a SIGUSR1, or
start if not running
stop-graceful - stop httpd (sending SIGWINCH to parent)
configtest - do a configuration syntax test
extreme-configtest - try to run httpd as nobody (detects more errors
by actually loading the configuration, but cannot
read SSL certificates)
probe - probe for the necessity of a reload, give
out the argument which is required for a reload.
(by comparing conf files with pidfile timestamp)
full-server-status - dump a full status screen; requires lynx or w3m
and mod_status enabled
server-status - dump a short status screen; requires lynx or w3m
and mod_status enabled
help - this screen
optional server flags are passed through to httpd.
