# This script byte-compiles all `.el' files which are part of its
# arguments, using GNU Emacs, and put the resulting `.elc' files into
# the current directory, so disregarding the original directories used
# in `.el' arguments.
#
# This script manages in such a way that all Emacs LISP files to
# be compiled are made visible between themselves, in the event
# they require or load-library one another.
#
# Matthew Campbell <mattcampbell@pobox.com> modified this script to add the
# contents of the srcdir environment variable to the Emacs load-path
# variable, so that files in $srcdir (most likely other source files in the
# package) are visible to the file being compiled.  This is necessary because
# Makefiles generated by GNU automake call elisp-comp on one Lisp file at a
# time, but these Lisp files may depend on each other.  It was also necessary
# to modify the rule for compiling Lisp files to set the srcdir variable
# before calling elisp-comp.
