## URL Translations

SVN::RaWeb::Light supports URL translations. By enabling them (either on the URL or in the script that hosts the repository), they can translate a relative path within the hosted repository to a URL. The latter is usually a URL of the Subversioned resource, which can be manipulated directly using the `svn` client and other clients.

## CGI Parameters

Several parameters can be specified as CGI parameters on the URL location bar:

rev
  This parameter specifies the revision of the repository to browse. If unspecified, it defaults to the Subversion HEAD revision.
trans_user
  This is a multiple parameter. It specifies a list of user-defined URL translations. The format is the label of the translation followed by a comma followed by the URL of the translation relative to the root served by the script.
trans_hide_all
  When specified to a true value (for example "1") this variable disables all the pre-defined (i.e: non-user-specified) URL translations.
trans_no_list
  When specified to a true value, hides all the translations after the files and directories in the directory contents. It does not affect the URLs at the top.
