 +====== Support for InterWiki links ======
 +
 +//(since [[:​milestone:​0.10]])//​
 +
 +===== Definition =====
 +
 +An InterWiki link can be used for referring to a Wiki page
 +located in another Wiki system, and by extension, to any object
 +located in any other Web application,​ provided a simple URL 
 +mapping can be done.
 +
 +At the extreme, InterWiki prefixes can even be used to simply introduce
 +links to new protocols, such as `tsvn:` used by TortoiseSvn.
 +
 +===== Link Syntax =====
 +
 +<​code>​
 +<​target_wiki>​(:<​identifier>​)+
 +</​code>​
 +
 +
 +The link is composed by the targeted Wiki (or system) name,
 +followed by a colon (e.g. `MeatBall:​`),​
 +followed by a page specification in the target.
 +Note that, as for InterTrac prefixes, **InterWiki prefixes are case insensitive**.
 +
 +The target Wiki URL is looked up in the InterMapTxt wiki page, 
 +modelled after MeatBall:​InterMapTxt.
 +
 +In addition to traditional InterWiki links, where the target
 +is simply //​appended//​ to the URL, 
 +Trac supports parametric InterWiki URLs:
 +identifiers `$1`, `$2`, ... in the URL
 +will be replaced by corresponding arguments.
 +The argument list is formed by splitting the page identifier
 +using the ":"​ separator.
 +
 +===== Examples =====
 +
 +If the following is an excerpt of the InterMapTxt page:
 +
 +<​code>​
 +====== InterMapTxt ======
 +===== This is the place for defining InterWiki prefixes =====
 +
 +Currently active prefixes: [[:​[InterWiki]]]
 +
 +This page is modelled after the MeatBall:​InterMapTxt page.
 +In addition, an optional comment is allowed after the mapping.

 +Then, 
 +  * `MoinMoin:​InterWikiMap` should be rendered as MoinMoin:​InterWikiMap
 +   and the //title// for that link would be "​!InterWikiMap in MoinMoin"​
 +  * `Trac-ML:​4346` should be rendered as Trac-ML:​4346
 +   and the //title// for that link would be "​Message 4346 in Trac Mailing List"
