The gopher protocol, as defined by RFC 1436,
     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's URL Wrappers,
     and provides a helper function gopher_parsedir() to
     make sense of gopher formatted directory listings.
