     The gopher protocol, as defined by <link xlink:href="&url.rfc;1436">RFC 1436</link>,
     is generally considered the ancestor of the modern HTTP protocol.
     However, gopher was also intended to provide references to non-gopher
     resources including telnet, wais, nntp, and even http. This extension
     adds gopher support to PHP&apos;s <link linkend="wrappers">URL Wrappers</link>,
     and provides a helper function <function>gopher_parsedir</function> to
     make sense of gopher formatted directory listings.
