Template:!!/doc

This is a documentation subpage for Template:!!.
It contains usage information, categories, and other content that is not part of the original template page.

This is an auxiliary template that allows one to encode "||" (two pipes or vertical bars) within template parameters. If it is unnecessary to get a "||", it is better to use "||". However the "||" delimiter for a Wiki table has to be escaped by a template if it is used within a template.
