<para>
mailto automates the creation of mailto links and optionally
encodes them. Encoding e-mails makes it more difficult for
web spiders to pick up e-mail addresses off of your site.

<title>Technical Note</title>
<para>
javascript is probably the most thorough form of
encoding, although you can use hex encoding too.

<title>mailto</title>
<programlisting>
{mailto address="me@domain.com"}
{mailto address="me@domain.com" text="send me some mail"}
{mailto address="me@domain.com" encode="javascript"}
{mailto address="me@domain.com" encode="hex"}
{mailto address="me@domain.com" subject="Hello to you!"}
{mailto address="me@domain.com" cc="you@domain.com,they@domain.com"}
{mailto address="me@domain.com" extra='class="email"'}
OUTPUT:
&lt;a href="mailto:me@domain.com" &gt;me@domain.com&lt;/a&gt;
&lt;a href="mailto:me@domain.com" &gt;send me some mail&lt;/a&gt;
