Usage: d2cs [<options>]
	-m <FILE>:		set memory debug logging file to FILE
	-c <FILE>:		set configuration file to FILE
	-l <FILE>:		set log to FILE
	-h, --help:		show this help message and exit
	-v, --version:		show version information and exit
	-f, --foreground:	start in foreground mode (don`t daemonize)
	-s, --stderr:		log to stderr instead of logging to file

Notes:
	1.You should always use absolute path here for all FILE names
	2.-m option only works when compiled with USE_CHECK_ALLOC defined
