# 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
|
