### Commentary:

## This file copies a single lisp file into an XEmacs package hierarchy and
## performs the necessary magic so that it will be autoloaded at the next
## dump.

## Parameters:
##	$1 -- Full path to an XEmacsen later than 20.3
##	$2 -- Full path to a lisp file to install
##	$3 -- Full path to a lisp directory in an XEmacs package hierarchy
##	      This directory will be created if it does not exist.
##	      NOTE: the directory name should *not* end in a trailing slash


### Code:

if [ ! -f "${LISP_FILE}" -o ! -x "${XEMACS}" ]; then
	exit 1
fi

# Test for destination directory, creating if necessary
test -d "${DEST_DIR}" || mkdir "${DEST_DIR}"
test -d "${DEST_DIR}" || exit 1;

cp -p "${LISP_FILE}" "${DEST_DIR}" || exit 1;
