#Shell script for building and installing Emacs.

# Where to install all of Emacs's data files - the lisp code,
# documentation tree, and the architecture-dependent and -independent
# libaries.  The default definitions for the variables below are
# expressed in terms of this one, so you may not need to change them.
# set LIBROOT=/usr/local/lib/emacs-19.0
LIBROOT=/usr/local/emacs

# Emacs will search this path to find its elisp files.  This should be
# a colon-separated list of directories.  Strictly speaking, all the
# elisp files should go under DATADIR (below), since both elisp source
# and compiled elisp are completely portable, but it's traditional to
# give the lisp files their own subdirectory.
LISPPATH=/usr/local/emacs/local-lisp:/usr/local/emacs/lisp

# Emacs will look here for its architecture-independent files (like
# the tutorial and the zippy database).
DATADIR=/usr/local/emacs/share-lib

# Emacs will look here for its architecture-dependent files, like
# executables for its utilities.
LIBDIR=/usr/local/emacs/arch-lib

# The locking directory, where the Emacs locking code keeps track of
# which files are currently being edited.
# set LOCKDIR=${LIBROOT}/lock
LOCKDIR=/usr/local/emacs/lock

# This is where build-install should place the binaries people will
# want to run directly (like etags and Emacs itself).
BINDIR=/usr/local/bin
