# Info:
# This makefile is gnu-make spacific, other make systems needn't understand it
# This makefile generates include-file dependencies into *.d files in each build and then reuses these dependencies in the following builds
#
# Usage:
# To make a release build, call "make release=1"
# To make a debug build, call "make"
