# =====================================================================

#
# Notes
# -----
#
# - A useful resource for techniques to process Makefile dependencies:
# www.microhowto.info/howto/automatically_generate_makefile_dependencies.html
#
# - Using -O0 rather than -O3 during development may reduce compilation time
# significantly.
