# Makefile (C) 2006-2008, Aurélien Croc (AP²C)
#
# This project is under the GPL Licence
#
# Available MAKE options:
# * V sets to 1 for verbose mode
#
# Available variables in module.mk :
# * SUBDIRS
# * MODE = {default,debug,optimized}
# * CFLAGS
# * CXXFLAGS
# * LDFLAGS
# * DEBUG_CFLAGS
# * DEBUG_CXXFLAGS
# * OPTIMIZED_CFLAGS
# * OPTIMIZED_CXXFLAGS
# * TARGETS
# * GENERIC_TARGETS
# * PRE_GENERIC_TARGETS
# * directory1_directory2_file_ext_FLAGS
#
# Each project must be listed in the TARGETS variable. Next:
# * project1_SRC
# * project1_LIB
# * project1_CFLAGS
# * project1_LDFLAGS
# * project1_MODULES
# * project1_CXXFLAGS
# * ...
#
# This Makefile will generate:
# * project1_TARGET
# * project1_OBJ
#
#
# In the file rules.mk:
#
# You can add your own rules
#
# To add a new target file support, please add the target extension in the
# TARGET_RULES variable and define the function targetDefinition_{extension}.
# This function will be called with one parameters: the target name
# Like the examples above, use $(value $(1)_TARGET) or _OBJ, .. to access
# to useful informations
#
#
# /!\ = Please do your modifications in the module.mk file = /!\
