# make all to compile and build Emacs.
# make install to install it (installs in-place, in `bin' subdir of top dir).
# make TAGS to update tags tables.
#
# make clean or make mostlyclean
# Delete all files from the current directory that are normally
# created by building the program. Don't delete the files that
# record the configuration. Also preserve files that could be made
# by building, but normally aren't because the distribution comes
# with them.
#
# Delete `.dvi' files here if they are not part of the distribution.
#
# make distclean
# Delete all files from the current directory that are created by
# configuring or building the program. If you have unpacked the
# source and built the program without creating any other files,
# `make distclean' should leave only the files that were in the
# distribution.
#
# make maintainer-clean
# Delete everything from the current directory that can be
# reconstructed with this Makefile. This typically includes
# everything deleted by distclean, plus more: *.elc files,
# C source files produced by Bison, tags tables, info files,
# and so on.
#
# make extraclean
# Still more severe - delete backup and autosave files, too.
# This gork is required for those who use a Unix-style shell, and
# have SHELL in the environment pointing to it. Here we force
# Make to use COMMAND.COM instead. This Makefile won't work otherwise.
# (The /xyzzy directory is used to minimize the chance that someone
# actually has such a directory with an incompatible command.com. We
# used to have /dos there, but some Windows installations have an old
# version of DOS stashed in that directory, and command.com from there
# won't run on Windows, complaining about "Incorrect DOS version".
# Make will look up PATH for the shell executable, so the directory name
# is not important.)
SHELL=/xyzzy/command
MAKESHELL=/xyzzy/command
# Generate a full pathname of the top-level installation directory
top_srcdir := $(subst \,/,$(shell cd))
# Q: Do we need to bootstrap?
# A: Only if we find msdos/autogen/Makefile.in, i.e. we are building out of
# a VCS-checkout (not a release), and src/b-emacs.exe does not exist.
# This avoids building a bootstrap-emacs and recompiling Lisp files
# when building a pretest/release tarball. Recompiling Lisp files
# is BAD because lisp/Makefile.in requires a Unixy shell.

ifneq ($(wildcard msdos/autogen/Makefile.in),)

# Subdirectories to run Make. `lisp' is not included because the
# compiled lisp files are part of the distribution. (If we are
# bootstrapping, the src target will run Make in `lisp' as well.)

# Pass to src/Makefile.in an additional BOOTSTRAPEMACS variable which

# src/Makefile.in uses it to implement conditional dependencies, so that
# files that need bootstrap-emacs to be built do not additionally need
# to be kept fresher than b-emacs.exe. Otherwise changing a single
# file src/foo.c forces dumping a new bootstrap-emacs, then re-byte-compiling
# all preloaded elisp files, and only then dump the actual src/emacs, which
# is not wrong, but is overkill in 99.99% of the cases.
