This is a hack which provides the same functionality as the #ifexist parser function. It is used to circumvent the limitation of expensive parser function calls. Since this template might even be more resource expensive than the #ifexist function, it should generally be avoided to use it.
This template should not be used to check the existence of articles/templates that make use of Variables.
