Template:If en
From dankwiki
{{#ifeq: if en|If en |{{{1}}}| }}
Do not transclude this in PD help pages (Help namespace), since it seem to break the PD help guidelines, in that, this template name is not suitable to be included in a fresh wiki installation. For PD help pages, use Template:Help/If en instead.
Example
{{#ifeq: if en|If en || }}
