# DIST: This is the distribution Makefile for Emacs.  configure can
# DIST: make most of the changes to this file you might want, so try
# DIST: that first.

# make all	to compile and build Emacs.
# make install	to install it.
# make install.sysv to install on system V.  Note that on system V you
#		must change mandir to /usr/local/man/man1.
# make install.xenix  to install on Xenix.
# make install.aix    to install on AIX.
# 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 realclean
#      Delete everything from the current directory that can be
#      reconstructed with this Makefile.  This typically includes
#      everything deleted by distclean, plus more: C source files
#      produced by Bison, tags tables, info files, and so on.
#
# make extraclean
#      Still more severe - delete backup and autosave files, too.

# ==================== Where To Install Things ====================

# 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.
prefix=/usr/local

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

# Where to install Emacs and other binaries that people will want to
# run directly (like etags).
bindir=${exec_prefix}/bin

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

# Where to install and expect the files that Emacs modifies as it
# runs.	 These files are all architecture-independent. Right now, the
# only such data is the locking directory; ${lockdir} is a
# subdirectory of this.
statedir=${prefix}/lib

# Where to install and expect executable files to be run by Emacs
# rather than directly by users, and other architecture-dependent
# data.	 ${archlibdir} is a subdirectory of this.
libdir=${exec_prefix}/lib

# Where to install Emacs's man pages, and what extension they should have.
mandir=${prefix}/man/man1
manext=.1

# Where to install and expect the info files describing Emacs.	In the
# past, this defaulted to a subdirectory of ${prefix}/lib/emacs, but
# since there are now many packages documented with the texinfo
# system, it is inappropriate to imply that it is part of Emacs.
infodir=${prefix}/info

# Where to find the source code - setting this to anything but
# . doesn't work yet.  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.
srcdir=.

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

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

# Where to install the elisp files distributed with Emacs.  This
# includes the Emacs version, so that the lisp files for different
# versions of Emacs will install themselves in separate directories.
lispdir=${datadir}/emacs/${version}/lisp

# Directories Emacs should search for elisp files specific to this
# site (i.e. customizations), before consulting ${lispdir}.  This
# should be a colon-separated list of directories.
locallisppath=${datadir}/emacs/local-lisp

# Where Emacs will search to find its elisp 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.
lisppath=${locallisppath}:${lispdir}

# Where Emacs will search for its elisp 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.  It's usually identical to lisppath, except that the entry
# for the directory containing the installed lisp files has been
# replaced with ../lisp.  This should be a colon-separated list of
# directories.
buildlisppath=../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=${datadir}/emacs/${version}/etc

# Where to create and expect the locking directory, where the Emacs
# locking code keeps track of which files are currently being edited.
lockdir=${statedir}/emacs/lock

# 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.

# ==================== Cleaning up and miscellanea ====================

### `clean'
###	 Delete all files from the current directory that are normally

###	 by building, but normally aren't because the distribution comes
###	 with them.
### `mostlyclean'
###	 Like `clean', but may refrain from deleting a few files that
###	 people normally don't want to recompile.  For example, the
###	 `mostlyclean' target for GCC does not delete `libgcc.a', because
###	 recompiling it is rarely necessary and takes a lot of time.

	if [ `(cd ${etcdir} ; /bin/pwd` != `(cd etc; /bin/pwd)` ] ; then \
	  cd etc; $(MAKE) clean; \
	else true; \
	fi

### `distclean'
###	 Delete all files from the current directory that are created by
###	 configuring or building the program.  This should leave only the
###	 files that would be in the distribution.
distclean:
	for i in ${SUBDIR}; do (cd $$i; $(MAKE) ${MFLAGS} distclean); done

### `realclean'
###	 Delete everything from the current directory that can be

###	 everything deleted by distclean, plus more: C source files
###	 produced by Bison, tags tables, info files, and so on.
realclean:
	for i in ${SUBDIR}; do (cd $$i; $(MAKE) ${MFLAGS} realclean); done
	(cd lock; rm *)

### This doesn't actually appear in the coding standards, but Karl
