# Makefile for Coq
#
# To be used with GNU Make >= 3.81.
#
# This Makefile is now separated into Makefile.{common,build,doc}.
# 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://miller.emu.id.au/pmiller/books/rmch/
# 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.
#
# Specific command-line options to this Makefile:
#
# make VERBOSE=1           # restore the raw echoing of commands
# make NO_RECALC_DEPS=1    # avoid recomputing dependencies
#
# Nota: the 1 above can be replaced by any non-empty value
#
