=head1 NAME

AnyEvent::XMPP::SimpleConnection - Low level TCP/TLS connection

=head1 SYNOPSIS

   package foo;
   use AnyEvent::XMPP::SimpleConnection;

   our @ISA = qw/AnyEvent::XMPP::SimpleConnection/;

=head1 DESCRIPTION

This module only implements the basic low level socket and SSL handling stuff.
It is used by L<AnyEvent::XMPP::Connection> and you shouldn't mess with it :-)

(NOTE: This is the part of AnyEvent::XMPP which I feel least confident about :-)
