### Commentary:

# make all	to compile and build Emacs.
# make install	to install it.
# 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.
#
# make bootstrap
#      Removes all the compiled files to force a new bootstrap from a
#      clean slate, and then build in the normal way.

# Either yes or no depending on whether this is a relocatable Emacs.app.
ns_self_contained=@ns_self_contained@

# The default location for installation.  Everything is placed in
# subdirectories of this directory.  The default values for many of
# the variables below are expressed in terms of this one, so you may
# not need to change them.  This defaults to /usr/local.
prefix=@prefix@

# Like `prefix', but used for architecture-specific files.
exec_prefix=@exec_prefix@

# Where to install Emacs and other binaries that people will want to
# run directly (like etags).

# The root of the directory tree for read-only architecture-independent
# data files.  ${datadir}, ${infodir} and ${mandir} are based on this.
datarootdir=@datarootdir@

# Where to install architecture-independent data files.	 ${lispdir}
# and ${etcdir} are subdirectories of this.
datadir=@datadir@

# Where to install and expect the files that Emacs modifies as it
# runs.  These files are all architecture-independent.
# Right now, this is not used.
sharedstatedir=@sharedstatedir@

# Where to install and expect executable files to be run by Emacs
# rather than directly by users (and other architecture-dependent
# data, although Emacs does not have any).  The executables
# are actually installed in ${archlibdir}, which is (normally)
# a subdirectory of this.
libexecdir=@libexecdir@

# Where to install Emacs's man pages.
# Note they contain cross-references that expect them to be in section 1.
mandir=@mandir@

# Directory for local state files for all programs.
localstatedir=@localstatedir@

# Where to look for bitmap files.
bitmapdir=@bitmapdir@

# Where to find the source code.  The source code for Emacs's C kernel is
# expected to be in ${srcdir}/src, and the source code for Emacs's
# utility programs is expected to be in ${srcdir}/lib-src.  This is
# set by the configure script's `--srcdir' option.

# ==================== Emacs-specific directories ====================

# These variables hold the values Emacs will actually use.  They are
# based on the values of the standard Make variables above.

# Emacs.  This includes the Emacs version, so that the
# lisp files for different versions of Emacs will install
# themselves in separate directories.

# site (i.e. customizations), before consulting ${standardlisppath}.
# This should be a colon-separated list of directories.
locallisppath=@locallisppath@

# Where Emacs will search to find its lisp files.  Before
# changing this, check to see if your purpose wouldn't
# better be served by changing locallisppath.  This
# should be a colon-separated list of directories.
# The default is ${locallisppath}:${standardlisppath}.
lisppath=@lisppath@

# Where Emacs will search for its lisp files while
# building.  This is only used during the process of
# compiling Emacs, to help Emacs find its lisp files
# before they've been installed in their final location.
# This should be a colon-separated list of directories.
# Normally it points to the lisp/ directory in the sources.
buildlisppath=${srcdir}/lisp

# Where to install the other architecture-independent
# data files distributed with Emacs (like the tutorial,
# the cookie recipes and the Zippy database). This path
# usually contains the Emacs version number, so the data
# files for multiple versions of Emacs may be installed
# at once.
etcdir=@etcdir@

# Where to put executables to be run by Emacs rather than
# the user.  This path usually includes the Emacs version
# and configuration name, so that multiple configurations
# for multiple versions of Emacs may be installed at
# once.
archlibdir=@archlibdir@

# Where to put the docstring file.
docdir=@docdir@

# Where to install Emacs game score files.
gamedir=@gamedir@

# ==================== Utility Programs for the Build ====================

# Allow the user to specify the install program.
# Note that if the system does not provide a suitable install,
# configure will use build-aux/install-sh.  Annoyingly, it does
# not use an absolute path.  So we must take care to always run
# INSTALL-type commands from the directory containing the Makefile.

### Install the files that are machine-independent.
### Most of them come straight from the distribution; the exception is
### the DOC file, which is copied from the build directory.

## We delete each directory in ${COPYDESTS} before we copy into it;
## that way, we can reinstall over directories that have been put in
## place with their files read-only (perhaps because they are checked
## into RCS).  In order to make this safe, we make sure that the
## source exists and is distinct from the destination.

## We delete etc/DOC* because there may be irrelevant DOC files from
## other builds in the source directory.  This is ok because we just
## deleted the entire installed etc/ directory and recreated it.
## install-doc installs the relevant DOC.

## Note that the Makefiles in the etc directory are potentially useful
## in an installed Emacs, so should not be excluded.

## I'm not sure creating locallisppath here serves any useful purpose.
## If it has the default value, then the later write_subdir commands
## will ensure all these components exist.
## This will only do something if locallisppath has a non-standard value.
## Is it really Emacs's job to create those directories?
## Should we also be ensuring they contain subdirs.el files?
## It would be easy to do, just use write_subdir.

## Note that we use tar instead of plain old cp -R/-r because the latter
## is apparently not portable (even in 2012!).
## http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00278.html
## I have no idea which platforms Emacs supports where cp -R does not
## work correctly, and therefore no idea when tar can be replaced.
## See also these comments from 2004 about cp -r working fine:

###      is rarely necessary and takes a lot of time.

###
###      One exception, however: `make maintainer-clean' should not delete
###      `configure' even if `configure' can be remade using a rule in the
###      Makefile.  More generally, `make maintainer-clean' should not delete
###      anything that needs to exist in order to run `configure' and then
###      begin to build the program.
