# 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.

# Specific command-line options to this Makefile
#
# make GOTO_STAGE=N        # perform only stage N (with N=1,2)
# make VERBOSE=1           # restore the raw echoing of commands
# make NO_RECALC_DEPS=1    # avoid recomputing dependencies
# make NO_RECOMPILE_LIB=1  # a coqtop rebuild does not trigger a stdlib rebuild
#
# Nota: the 1 above can be replaced by any non-empty value
# More details in dev/doc/build-system*.txt


# FAQ: special features used in this Makefile
#
# * Order-only dependencies: |
#
# Dependencies placed after a bar (|) should be built before
# the current rule, but having one of them is out-of-date do not
# trigger a rebuild of the current rule.
# See http://www.gnu.org/software/make/manual/make.html#Prerequisite-Types
#
# * Annotation before commands: +/-/@
#
# a command starting by - is always successful (errors are ignored)
# a command starting by + is runned even if option -n is given to make
# a command starting by @ is not echoed before being runned
#
# * Custom functions
#
# Definition via "define foo" followed by commands (arg is $(1) etc)
# Call via "$(call foo,arg1)"
#
# * Useful builtin functions
#
# $(subst ...), $(patsubst ...), $(shell ...), $(foreach ...)
#
# * Behavior of -include
#
# If the file given to -include doesn't exist, make tries to build it,
# but doesn't care if this build fails. This can be quite surprising,
# see in particular the -include in Makefile.stage*
