-This plugin offers a `HTML::Template` loop that iterates over all or
-a subset of a page's parents. It also provides a few bonus
-possibilities, such as styling the parent links depending on their
-place in the path.

-
-Content
-=======
-
-This plugin provides one template loop, called `PARENTLINKS`, that
-returns the list of parent pages for the current page. Every returned
-path element has the following variables set:
-
-* `URL` (string): url to the current path element
-* `PAGE` (string): title of the current path element
-* `DEPTH` (positive integer): depth of the path leading to the
-  current path element, counting from the wiki's root, which has
-  `DEPTH=0`
-* `HEIGHT` (positive integer): distance, expressed in path elements,
-  from the current page to the current path element; e.g. this is
-  1 for the current page's mother, 2 for its grand-mother, etc.
-* `DEPTH_n` (boolean): true if, and only if, `DEPTH==n`
-* `HEIGHT_n` (boolean): true if, and only if, `HEIGHT==n`
-
-Usage
-=====
-
-The `DEPTH_n` and `HEIGHT_n` variables allow the template writer to
-skip arbitrary elements in the parents list: they are arbitrary
-page-range selectors.
-
-The `DEPTH` and `HEIGHT` variables allow the template writer to apply
-general treatment, depending on one of these variables, to *every*
-parent: they are counters.
-
-Basic usage
------------
-
-As in the default `page.tmpl`, one can simply display the list of
-parent pages:
-
-	<TMPL_LOOP NAME="PARENTLINKS">
-	<a href="<TMPL_VAR NAME=URL>"><TMPL_VAR NAME=PAGE></a>/ 
-	</TMPL_LOOP>
-	<TMPL_VAR TITLE>
-
-
-Styling parents depending on their depth
-----------------------------------------
-
-Say you want the parent links to be styled depending on their depth in
-the path going from the wiki root to the current page; just add the
-following lines in `page.tmpl`:
-
-	<TMPL_LOOP NAME="PARENTLINKS">
-	<a href="<TMPL_VAR NAME="URL">" class="depth<TMPL_VAR NAME="DEPTH">">
-	  <TMPL_VAR NAME="PAGE">
-	</a> / 
-	</TMPL_LOOP>
-
-Then write the appropriate CSS bits for `a.depth1`, etc.
-
-Skip some parents, style the others depending on their distance to the current page
------------------------------------------------------------------------------------
-
-Say you want to display all the parents links but the wiki homepage,
-styled depending on their distance to the current page; just add the
-following lines in `page.tmpl`:
-
-	<TMPL_LOOP NAME="PARENTLINKS">
-	<TMPL_IF NAME="DEPTH_0">
-	<TMPL_ELSE>
-	<a href="<TMPL_VAR NAME="URL">" class="height<TMPL_VAR NAME="HEIGHT">">
-	  <TMPL_VAR NAME="PAGE">
-	</a> / 
-	</TMPL_LOOP>
-
-Then write the appropriate CSS bits for `a.height1`, etc.
-
-Full-blown example
-------------------
-
-Let's have a look at a more complicated example; combining the boolean
-loop variables provided by this plugin (`IS_ROOT` and friends) and
-`HTML::Template` flow control structures, you can have custom HTML
-and/or CSS generated for some special path components; e.g.:
-
-	<!-- all parents, skipping mother and grand'ma, inside a common div+ul -->
-	<div id="oldestparents">
-	<ul>
-	<TMPL_LOOP NAME="PARENTLINKS">
-	  <TMPL_IF NAME="HEIGHT_2">
-	  <TMPL_ELSE>
-	    <TMPL_IF NAME="HEIGHT_1">
-	    <TMPL_ELSE>
-	      <li><a href="<TMPL_VAR NAME="URL">"><TMPL_VAR NAME="PAGE"></a></li>
-	    </TMPL_IF>
-	  </TMPL_IF>
-	</TMPL_LOOP>
-	</ul>
-	</div>
-	
-	<!-- dedicated div's for mother and grand'ma -->
-	<TMPL_LOOP NAME="PARENTLINKS">
-	  <TMPL_IF NAME="HEIGHT_2">
-	    <div id="grandma">
-	      <a href="<TMPL_VAR NAME="URL">"><TMPL_VAR NAME="PAGE"></a>
-	    </div>
-	  <TMPL_ELSE>
-	    <TMPL_IF NAME="HEIGHT_1">
-	      <div id="mother">
-		<a href="<TMPL_VAR NAME="URL">"><TMPL_VAR NAME="PAGE"></a>
-	      </div>
-	    </TMPL_IF>
-	  </TMPL_IF>
-	</TMPL_LOOP>
-	
-	<!-- eventually, the current page title -->
-	<TMPL_VAR NAME="TITLE">
-	</div>
+This plugin generates the links to a page's parents that typically appear
