# This file is generated with smake.sh.
# You can use this make file with instruction make to
# use one of build mode: debug, profile, develop, release.
# No need to call make clean if You make with other mode,
# because the Makefile containes rules for automatically clean.
# Some usage examples:
# CFLAGS="-march=core2 -mtune=core2" make
# LDFLAGS="-lexpat" make mode=profile
# Report bugs to <mecareful@gmail.com>
