Compress all js files (move JS files into src/ subdirectories)
BUT - fckconfig.js, fckeditor.js, and editor/js/fckeditorcode_ie.js can not be compressed with jsmin (it breaks IE 6, see ); run horde-compress.php with the --nojsmin flag for this files
Language files - editor/lang/src - must be compressed without YUI Compressor and ShrinkSafe compression; run horde-compress.php with the --noyui --noshrinksafe flags (Ticket 7359)
Files: js/map/OpenLayers.js also parts of js/map/{google.js, yahoo.js, ve.js, bing.js}, and js/map/lang
Local modifications:
We create a custom build, with some classes split out of the main !Openlayers.js file and into separate files to facilitate provider configuration. These files separate files also have additions written by Horde LLC to support Geocoding. See HordeMap for details on our custom build process.
