/*! \page perlmod_tree Perl Module Tree Nodes

<h2>Nodes in the documentation tree of the Perl Module output
format.</h2>

This is a description of the structure of the documentation tree in
<b>DoxyDocs.pm</b>.  Each item in the list below describes a node in
the tree, and the format of the description is as follows:

<ul>
<li>[ key =&gt; ] <b>Name</b> <i>(type)</i>.  Explanation of the content.
</ul>

Where

<ul>

<li>The "key =>" part only appears if the parent node is a hash.
"key" is the key for this node.

<li><b>"Name"</b> is a unique name for the node, defined in
DoxyModel.pm.

<li><i>"(type)"</i> is the type of the node: "string" for string
nodes, "hash" for hash nodes, "list" for list nodes, and "doc" for
documentation subtrees.  The structure of documentation subtrees is
not described anywhere yet, but you can look for example at
<b>doxylatex.pl</b> to see how to process it.

</ul>
