This is the Language help file for the Munsell ColorPicker. Its location is determined thus:
The root-level path is set in the JavaScript file, /assets/scripts/init.js. You can reset it by changing the urls.help property of the FM object.
The base of the filename comes from the Lang query-string parameter (default is En).
The filename extension comes the urls.helpExtension property of the FM object
The entire path/to/file.ext can be accessed from the helpInfo property of the FM object. FM.helpInfo is generated on page load by concatenating FM.urls.help + FM.Lang + FM.urls.helpExtension.
