The constructor for HTML::Template takes an optional argument names
"associate", which should point to an object (or reference to a list of
objects) that can("param").  Paramters in the template that are not
explicitly filled in using the param method of the HTML::Template object
are looked for by iterating through this list and calling
param($template_variable_name), and takes the first non-false value as
the correct one.

To reuse Ken's illustration:

    sub handler {
        my $r   = shift;
        my $apr = Apache::Request->new($r);
        my $t   = HTML::Template->new(associate => $apr,
                                      filename  => '/foo/bar.html');
        $apr->content_type('text/html');
        $apr->send_http_header;
        $apr->print( $t->output );
        return OK;
    }

    <form>
        <input name="foo" value="<TMPL_VAR NAME="foo">">
        <textarea name="text"><TMPL_VAR NAME="description"></textarea>
    </form>

For the template itself, "foo" will be looked for as $apr->param("foo"),
and description as $apr->param("description").
