# Makefile for Coq
#
# To be used with GNU Make.
#
# This is the only Makefile. You won't find Makefiles in sub-directories
# and this is done on purpose. If you are not yet convinced of the advantages
# of a single Makefile, please read
#    http://www.pcug.org.au/~millerp/rmch/recu-make-cons-harm.html
# before complaining.
# 
# When you are working in a subdir, you can compile without moving to the
# upper directory using "make -C ..", and the output is still understood
# by Emacs' next-error.
