Makefile

# The make-provided flags like MAKE and CC aren't set, on purpose.
# This is Linux-specific software, so we can depend on GNU make.

# Options:
#	nls	enable translations, default on
#	debug	enable debug symbols, default off
#	nostrip	disable stripping, default off
#	plain	apply neither -g nor -s.
