# Goal :
#	configuration utility for Eagle-USB modems
# Params :
#	h = display help
#	l = choose language (keep, auto or [LL])
#		keep => use previous language (read $LANG in eagle-usb.conf)
#		auto => use system language (given by $LANG var)
#		LL   => language you want to use (en, fr, pl...)
#	e = expert mode (additional choices)
# Params set by setvars :
#	USE_HOTPLUG=1		=> use hotplug
#	USE_IFUPDOWN=1		=> use ifup/ifdown scripts instead of ifconfig
#	SIMPLE=1			=> don't use hotplug nor ifup/ifdown

# the following line will be replaced by the absolute path of setvars
exit 123
