-# rc.d Script Runtime Options:
-#
-# start		- starts application normally
-# stop		- (softstop) stops all proxies and exits once all sessions are closed 
-# forcestop	- (immediate) stops all proxies and kills active sessions
-# reload	- hot-reconfig using "-sf" option (active sessions kept)
-# forcereload	- hot-reconfig using "-st" option (active sessions killed)
-# restart	- equiv to "stop" then "start"
-# configtest	- checks configuration file defined in haproxy_config

+# haproxy_profiles (str):	default: empty
+# Set to space-separated list of profiles: for each profile separate haproxy
