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.
