# Notes
################################################################################

# The purpose of the sed command is to make each `.d' file depend on all the
# source and header files that the corresponding `.o' file depends on. make then
# knows it must regenerate the dependencies whenever any of the source or header
# files changes.
# Each .d file also depends on the Makefile so that make regenerate the entire
# files when the Makefile is modified
#
# Each .o file of course depends of all the headers it may include thanks to the
# automatic dependance computation.
# Is also depends on the corresponding .d file so that we are sure it will be
# remade each time the dependancies are updated even if the files it depends have
# not changed. This is usefull when the Makefile is modified for example.
#
# At that time, all dependancies are included. Howewer a .d file should only be
# included if the corresponding .o needs to be re-made. I don't know how to do
# without calling another makefile to build the .d files.
