/**

 * "original template" from ./template/yoga (or any other than yoga)
 * will be replaced by a "replacer" if the replacer is linked to this "original template"
 * (and optionally, when the requested URL contains an "optional URL keyword").
 *
 * "Optional URL keywords" are those you can find after the module name in URLs.
 *
 * Therefore "Optional URL keywords" can be an active "permalink"
