+TracLinks are a fundamental feature of Trac, allowing easy hyperlinking between the various entities in the system — such as tickets, reports, changesets, Wiki pages, milestones, and source files — from anywhere WikiFormatting is used.
 
 TracLinks are generally of the form '''type:id''' (where ''id'' represents the number, name or path of the item) though some frequently used kinds of items also have short-hand notations.

 This can be seen as a kind of InterWiki link specialized for targeting other Trac projects.
 
-Any type of Trac link can be written in one Trac environment and actually refer to resources in another Trac environment. All that is required is to prefix the Trac link with the name of the other Trac environment followed by a colon. The other Trac environment must be registered on the InterTrac page. 
-
-A distinctive advantage of InterTrac links over InterWiki links is that the shorthand form of Trac links (e.g. `{}`, `r`, `#`) can also be used. For example if T was set as an alias for Trac, links to Trac tickets can be written #T234, links to Trac changesets can be written [trac 1508].

-=== Version Control related links
-
-It should be noted that multiple repository support works by creating a kind of virtual namespace for versioned files in which the toplevel folders correspond to the repository names. Therefore, in presence of multiple repositories, a ''/path'' specification in the syntax of links detailed below should start with the name of the repository. If omitted, the default repository is used. In case a toplevel folder of the default repository has the same name as a repository, the latter "wins". One can always access such folder by fully qualifying it. The default repository can be an alias of a named repository, or conversely, it is always possible to create an alias for the default repository, ask your Trac administrator.
