# TODO:
#  - allow extra dependencies for foobar.pdf in local Makefile (use ::)
#  - extra target make list-images, make list-tex...
#  - using include $(RULES) instead of $(MAKE1), and GNU remaking of
# $(RULES) when necessary.
#  + inclusion of TeX files and packages/classes
#  - auto determine whether TeX / LaTeX / ConTeXt / LuaTeX / ...
#  - factor tex log coloring via a function
#  - allow empty colors
#  - prevent control going back to Makefile to allow calls such as
#    make -f /some/where/this/Makefile
