Documentation[create] [purge]

Editors can experiment in this template's sandbox (create | mirror) and testcases (create) pages.
Add categories to the /doc subpage. Subpages of this page.

This template replaces the #ifexist parser function, and functions as a workaround for the Expensive parser function calls problem.

Built in #ifexist usage:

{{#ifexist: ''page'' | ''result if exists'' | ''result if does not exist''}}

New {{ifexist}} usage:

{{ifexist| ''page'' | ''result if exists'' | ''result if does not exist''}}
