#Shell script for building and installing Emacs.

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

# The default location for installation.  Everything is placed in
# subdirectories of this directory.  This directory must exist when
# you start installation.  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

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

# A directory under which we will install many of Emacs's files.  The
# default values for many of the variables below are expressed in
# terms of this one, so you may not need to change them.
emacsdir=${prefix}/emacs-19.0

# Where to install and expect the architecture-independent data files
# (like the tutorial and the Zippy database).
datadir=${emacsdir}/etc

# Where to install the elisp files distributed with Emacs.  Strictly
# speaking, all the elisp files should go under datadir (above), since
# both elisp source and compiled elisp are completely portable, but
# it's traditional to give the lisp files their own subdirectory.
lispdir=${emacsdir}/lisp

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

# 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.
statedir=${emacsdir}

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

# Where to install and expect executable files to be run by Emacs
# rather than directly by users, and other architecture-dependent
# data.
libdir=${emacsdir}/arch-lib

# Where to install Emacs's man pages.
mandir=/usr/man/man1

# 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
