-The `trail` directive is supplied by the [[plugins/contrib/trail]]
-plugin. It sets options for the trail represented by this page. Example usage:
-
-    \[[!trail sort="meta(date)" circular="no" pages="blog/posts/*"]]
-
-The available options are:
-
-* `sort`: sets a [[ikiwiki/pagespec/sorting]] order; if not specified, the
-  items of the trail are ordered according to the first link to each item
-  found on the trail page
-
-* `circular`: if set to `yes` or `1`, the trail is made into a loop by
-  making the last page's "next" link point to the first page, and the first
-  page's "previous" link point to the last page
-
-* `pages`: add the given pages to the trail

-The `trailinline` directive is supplied by the [[plugins/contrib/trail]]
-plugin. It behaves like the [[trail]] and [[inline]] directives combined.
-Like [[inline]], it includes the selected pages into the page with the
-directive and/or an RSS or Atom feed; like [[trail]], it turns the
-included pages into a "trail" in which each page has a link to the
-previous and next pages.

-    \[[!inline sort="meta(date)" circular="no" pages="blog/posts/*"]]

-All the options for the [[inline]] and [[trail]] directives are valid.

-The `show`, `skip` and `feedshow` options from [[inline]] do not apply
-to the trail.

-The `traillink` directive is supplied by the [[plugins/contrib/trail]] plugin.
-It generates a visible [[ikiwiki/WikiLink]], and also adds the linked page to
-the trail represented by the page containing the directive.
-
-In its simplest form, the first parameter is like the content of a WikiLink:
-
-    \[[!traillink some_other_page]]
-
-The displayed text can also be overridden, either with a `|` symbol or with
-a `text` parameter:
-
-    \[[!traillink Click_here_to_start_the_trail|some_other_page]]
-    \[[!traillink some_other_page text="Click here to start the trail"]]
