* Themes are directories with some expected sub-directories and files
* in them. They're found in either local/theme (for locally-installed themes)
* or theme/ subdir of installation dir.
+ *
+ * Note that the 'local' directory can be overridden as $config['local']['path']
+ * and $config['local']['dir'] etc.
*
* This used to be a couple of functions, but for various reasons it's nice
* to have a class instead.
