+= InterTrac Links
+
+Trac supports a convenient way to refer to resources of other Trac servers, from within the Wiki markup. An !InterTrac link can be seen as a scoped TracLinks. It is used for referring to a Trac resource located in another Trac environment. A resource can be a wiki page, changeset, ticket or milestone. 
+
+== List of Active InterTrac Prefixes
+
+[[InterTrac]]
+
+== Link Syntax
+
+Simply use the name of the other Trac environment as a prefix, followed by a colon, ending with the resource located in the other environment:
+
+{{{
+<target_environment>:<TracLinks>
+}}}
+
+The other resource is specified using a regular TracLinks, of any flavor.
+
+That target environment name is either the real name of the environment or an alias for it. 
+The aliases are defined in the `trac.ini` file, see below.
+The prefix is case insensitive.
+
+If the InterTrac link is enclosed in square brackets, like `[th:WikiExtrasPlugin]`, the InterTrac prefix is removed in the displayed link like a normal link resolver would be, ie the above would be displayed as `WikiExtrasPlugin`.
+
+For convenience, there is also an alternative short-hand form, where an alias can be used as an immediate prefix for the identifier of a ticket, changeset or report, eg `#T234`, `[T1508]`, `[trac 1508]`.
+
+== Examples
+
+It is necessary to set up a configuration for the InterTrac facility.
+This configuration has to be done in the TracIni file, `[intertrac]` section, for example:
+
+{{{#!ini
+[intertrac]
+# -- Example of setting up an alias:
+t = trac
+
+# -- Link to an external Trac:
+trac.title = Edgewall's Trac for Trac
+trac.url = http://trac.edgewall.org
+}}}
+
+The `.url` is mandatory and is used for locating the other Trac.
+This can be a relative URL in case that Trac environment is located on the same server.
+
+The `.title` information is used in a tooltip, ie when hovering the cursor over an InterTrac link.
+
+Now, given the above configuration, one could create the following links:
+ * to this InterTrac page:
+   * `trac:wiki:InterTrac` trac:wiki:InterTrac
+   * `t:wiki:InterTrac` t:wiki:InterTrac
+   * Keys are case insensitive: `T:wiki:InterTrac` T:wiki:InterTrac
+ * to the ticket #234:
+   * `trac:ticket:234` trac:ticket:234
+   * `trac:#234` trac:#234 
+   * `#T234` #T234
+ * to the changeset [1912]:
+   * `trac:changeset:1912` trac:changeset:1912
+   * `[T1912]` [T1912]
+ * to the log range [3300:3330]:
+   * `trac:log:@3300:3330` trac:log:@3300:3330  
+   * `[trac 3300:3330]` [trac 3300:3330]
+   * finally, to link to the start page of a remote trac, simply use its prefix followed by ':', inside an explicit link. Example: `[th: Trac Hacks]` (note that the ''remote'' Trac has to run Trac >= 0.11 for this to work'')
+
+The generic form `intertrac_prefix:module:id` is translated to the corresponding URL `<remote>/module/id`, shorthand links are specific to some modules (e.g. !#T234 is processed by the ticket module) and for the rest (`intertrac_prefix:something`), we rely on the TracSearch#quickjump facility of the remote Trac.
