# Rules for automatic header dependency tracking.

# This is somewhat similar to what automake does, but relies on compiler
# support. The result is much simpler.
#
# So, here is what happens :We instruct the compiler via some flags to
# create a "build/deps/FOO.d" file whenever it compiles "FOO.c". This file
# encodes the header dependencies of "FOO.c" in a way that make can read
# (i.e. simply as a bunch of make targets with dependencies). Then, to
# let make track the header dependencies, we include the *.d files.
#
# For a detailed explanation of a very similar scheme, read this:
# https://make.mad-scientist.net/papers/advanced-auto-dependency-generation/

# GAP_XYZ with the content of file cnf/GAP-XYZ. Do nothing if they
# match. Otherwise, write GAP_XYZ into cnf/GAP-XYZ. By only writing

# The files cnf/GAP-XYZ in turn now allow us to rebuild things if any of
