# Note on generic rules and dependancies
################################################################################

# Note on dependancies: each .c file is associated with a .d file, which
# depends of it. The .o file associated with a .c file depends of the .d, of the
# .c itself, and of Makefile. The .d files are stored in a separate .dep/
# directory.
# The dep directory should be ignored by CVS.

# Note on inclusions: depending of the target, the dependancies files must
# or must not be included. The problem is that if we ask make to include a file,
# and this file does not exist, it is made before it can be included. In a
# general way, a .d file should be included if and only if the corresponding .o
# needs to be re-made.

# Two makefiles are used: the main one (this one) has regular generic rules,
# except for .o files, for which it calls the object Makefile. Dependancies
# are not included in this file.
# The object Makefile known how to make a .o from a .c, and includes
# dependancies for the target, but only those required.
