# 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.

# add -DUSG for SysV movemail and timer
# For Xenix, add the following for movemail:
#  LOADLIBES= -lx
# For Mips, the following is needed for who knows what.
#  LOADLIBES = -lmld /usr/bsd43/usr/lib/libc.a

# Avoid trouble on systems where the `SHELL' variable might be
# inherited from the environment.
SHELL = /bin/sh

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

# Where to find the source code.  This is
# set by the configure script's `--srcdir' option.
# However, the value of ${srcdir} in this makefile
# is not identical to what was specified with --srcdir.
# The variable here has `/lib-src' added at the end.
srcdir=@srcdir@/lib-src
VPATH=@srcdir@/lib-src

# ==================== 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 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=${libdir}/emacs/${version}/${configname}

# ====================== Developer's configuration =======================

# The following assignments make sense if you're running Emacs on a single
# machine, one version at a time, and  you want changes to the lisp and etc
# directories in the source tree to show up immediately in your working
# environment.  It saves a great deal of disk space by not duplicating the
# lisp and etc directories.
#
# archlibdir=${srcdir}/bin

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

# Allow the user to specify the install program.
INSTALL = install
INSTALLFLAGS = -c
INSTALL_PROGRAM = ${INSTALL}
INSTALL_DATA = ${INSTALL}

# ============================= Targets ==============================

# Things that a user might actually run, which should be installed in bindir.

INSTALLABLE_SCRIPTS = rcs-checkin

# Things that Emacs runs internally, or during the build process,
# which should not be installed in bindir.
UTILITIES= test-distrib make-path wakeup make-docfile digest-doc sorted-doc \
