<p>
This is a very simple Template Toolkit Plugin interface to the
<code>CGI</code> module. A <code>CGI</code> object will be instantiated
via the following directive:
</p>
<pre><span class="tt">[% USE CGI %]</span></pre>
<p>
<code>CGI</code> methods may then be called as follows:
</p>
<pre><span class="tt">[% CGI.header %]</span>
<span class="tt">[% CGI.param('parameter') %]</span></pre>
<p>
An alias can be used to provide an alternate name by which the object
should be identified.
</p>
<pre><span class="tt">[% USE mycgi = CGI %]</span>
<span class="tt">[% mycgi.start_form %]</span>
<span class="tt">[% mycgi.popup_menu({ Name => 'Color'
Values => [ 'Green' 'Black' 'Brown' ] }) %]</span></pre>
<p>
Parenthesised parameters to the <code>USE</code> directive will be passed
to the plugin constructor:
</p>
<pre><span class="tt">[% USE cgiprm = CGI('uid=abw&name=Andy+Wardley') %]</span>
<span class="tt">[% cgiprm.param('uid') %]</span></pre>
</div>

<a href="#body" class="top" title="Back up to the top of the page" >Top</a>
</div>
<div class="body">
<p>
In addition to all the methods supported by the <code>CGI</code> module,
this plugin defines the following.
</p>
<div class="subsection">
<div class="head">
<h2 id="method_params" class="method" onclick="switch_subsection(this)" title="Click title to show/hide sub-section content.">params()</h2>
<a href="#body" class="top" title="Back up to the top of the page" >Top</a>
</div>
<div class="body">
<p>
This method returns a reference to a hash of all the <code>CGI</code>
parameters. Any parameters that have multiple values will be returned as
lists.
</p>
<pre><span class="tt">[% USE CGI('user=abw&item=foo&item=bar') %]</span>
<span class="tt">[% CGI.params.user %]</span> # abw
<span class="tt">[% CGI.params.item.join(', ') %]</span> # foo, bar</pre>
