# With the One Makefile, you never have to remember to update the list of
# objects you need to link your programs. It is designed to behave (almost)
# exactly the way you expect a Makefile to act - which cannot be said of
# automake, cmake, or qmake.
#
# The One Makefile lives under the name 'real.make', because it is
# reponsible for doing all the actual building, but it is not the file
# that the user actually calls (using make) directly. The reason for this
# is that the One Makefile requires a certain environment that it cannot
# arrange for on its own.
#
# Specifically:
#   The -r and -R flags must be passed.
#   A list of variables must be included, but regenerating Makefile from
#   Makefile.in is time-consuming, so real.make actually *includes* the
#   file that called it.
#
# For an example of how to do this safely, look at the Makefile.in shipped
# by TMWA. Of course, you could use any other mechanism to generate a
# Makefile, as long as it supplies the appropriate list of variables.


# TODO:
# 1. Implement support for static libraries
#   This should be trivial.
# 2. Implement support for shared libraries
#   This requires building two different .o files and such.
# 3. Implement support for mixed C and C++ source trees
#   This just requires writing more patsubst in various places
#   At that point, they should *probably* be refactored out into functions.
#   However, it would be hard to allow linking some binaries as pure C.
#   Unless maybe we should use .c.o and .cpp.o ?
# 4. See if something can be done about all the mkdirs.
# 5. Remove the few (obvious) bits that are hard-coded for TMWA.
# 6. Handle testing better. I'm guessing I should actually compile just
#   one foo_test.cpp file into each executable test ...
# 7. Refactor into several files after all. We need extensibility!
#
# IWBNMI:
# 1. Add 'make check' and 'make installcheck'.
# 2. 'make distclean' should remove "anything that ./configure created".
# 3. 'make dist' should be implemented. Git only or not?
# 4. 'make install' should install documentation.
# 5. Split 'make install-exec' and 'make install-data'. Beware etc and var!
# 6. '--program-prefix' and '--program-suffix' (easy). What about sed?
# 7. Support DESTDIR during 'make install' (URGENT).
# 8. 'make distcheck' using the 'make dist' tarball?
# 9. Add rules for gettext.
# 10. Support per-target build flags? (requires renaming)

# The major problem is that it's usually encoded in the PUA

# 1: Include the contents of the current %.d file ($1).

# 4: Remove all non-deps - clutter and lonely headers.
# 5: Prevent infinite loops later by filtering out deps we've already seen.
# 6: Merge new deps into the existing dep list.
# 7: Recurse over all new deps (see 5).
