### update-elc.sh --- recompile all missing or out-or-date .elc files
# Author: Jamie Zawinski <jwz@lucid.com>
# Maintainer: Ben Wing <ben.wing@Eng.Sun.COM>
# Created: ?
# Version: 1.0

# Keywords: recompile .el .elc
### Commentary:
## Recompile all .elc files that need recompilation. Requires a working
## version of 'xemacs'. Correctly handles the case where the .elc files
## are missing; thus you can execute 'rm lisp/*/*.elc' before running
## this script. Run this from the parent directory of 'src', 'lisp',
## and 'etc'. (If this is a Sun workspace, you can run it from
## 'era-specific' instead.)
set -eu
# This means we're running in a Sun workspace
if [ -d ../era-specific ]; then
cd ../editor
fi
# get to the right directory
if [ ! -d ./lisp ]; then
if [ -d ../lisp ]; then
cd ..
else
echo $0: neither ./lisp/ nor ../lisp/ exist
exit 1
