-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.

-[[!toc ]]
-
-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>
