This module automatically generates either an external link or an internal link, dependent on whether it is given a link with a protocol or not.
Understand that using this module will mean that links to things like the redirects in will result in external links being generated. This may not always be the desired result, so it should only be used where a wikilink that looks like a URL is implausible for the value the module is passed.

link title is an optional parameter, which if used will be set as the piped link for internal links like this, or the link title for external links like this.
