+= Support for InterWiki links
+[[PageOutline(2-5,Contents,pullout)]]
+
+== 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.
+
+InterWiki prefixes can even be used to introduce links to new protocols, such as `tsvn:` used by [trac:TortoiseSvn TortoiseSvn].
+
+== Link Syntax
+
+{{{
+<target_wiki>(:<identifier>)+
+}}}
+
+The link is composed by the targeted Wiki (or system) name, followed by a colon, eg `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 [TracIni#interwiki-section "[interwiki]"] section of TracIni and in the InterMapTxt wiki page, modeled after MeatBall:InterMapTxt. If a prefix is defined in both the `[interwiki]` section and InterMapTxt, the `[interwiki]` section takes precedence.
+
+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.
+
+== [TracIni#interwiki-section "[interwiki]"]
+
+Every option in the `[interwiki]` section in TracIni defines one InterWiki prefix. The option name defines the prefix. The option value defines the URL, optionally followed by a description separated from the URL by whitespace. Parametric URLs are supported as well.
+
+'''Example:'''
+{{{#!ini
+[interwiki]
+MeatBall = http://www.usemod.com/cgi-bin/mb.pl?
+PEP = http://www.python.org/peps/pep-$1.html Python Enhancement Proposal $1
+tsvn = tsvn: Interact with TortoiseSvn
+}}}
+
+== Examples
+
+For the following excerpt of the InterMapTxt page:
+
+{{{
+= 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.
