# Makefile for the   GNU Emacs Lisp Reference Manual.
#
# 11 August 1990

# Redefine `TEX' if `tex' does not invoke plain TeX. For example:
# TEX=platex

TEX=tex
MAKE=make

# Where the TeX macros are kept:
texmacrodir = /usr/local/lib/tex/macros

# Where the Emacs hierarchy lives ($EMACS in the INSTALL document for Emacs.)
# For example: 
# emacslibdir = /usr/local/gnu/lib/emacs

# Directory where Emacs is installed, by default:
emacslibdir = /usr/local/emacs

# Unless you have a nonstandard Emacs installation, these shouldn't have to 
# be changed.
prefix = /usr/local
infodir = ${prefix}/info

# The name of the manual:

VERSION=2.4.2
manual = elisp-manual-19-$(VERSION)

# Uncomment this line for permuted index.
# permuted_index = 1
