# Adjust the variables in (@> "Part I") to customize the build
# and install process. See the file (@file :file-name "./README" :display "README") for more details
# on customizing the intialization the .emacs file itself.
# Only change (@> "Part II") if you know what you are doing.
#
# Overview:
#
# To build and install a byte-compiled initialization file
# do the following:
#
#    make
#    make install
#    make clean  
#
# Be sure to verify successful compilation before proceeding to the
# second step. Emacs will give some compilation warnings which you can
# probably ignore. You can set INSTALL on the command line to
# change the final init file name and location;
# see (@> "INSTALL*") below for more options.
#
# To build and install an emacs lisp file, do the following:
#
#    make elisp
#    make install INSTALL_SUFX=.el
#    make fullclean  
#
# Again see (@> "INSTALL*") below for more options.
#
# By doing
#
#    make archive
#
# you can save a copy of these files in a compressed
# archive. The tag ARCHIVE allows you to specify the
# name and location of the archive file.
# See (@> "ARCHIVE*") below for more details.
#
# Note: This makefile follows GNU make conventions,
# particularly in the use of functions for the
# specification of the INSTALL tag.
