This module provides a standard socket-like interface for Python
for tunneling connections through SOCKS proxies.

Minor modifications made by Christopher Gilbert (http://motomastyle.com/) for
use in PyLoris (http://pyloris.sourceforge.net/).

Minor modifications made by Mario Vilas (http://breakingcode.wordpress.com/)
mainly to merge bug fixes found in Sourceforge.

    Attempts to replace a module's socket library with a SOCKS socket. Must set
    a default proxy using setdefaultproxy(...) first.
    This will only work on modules that import socket directly into the
    namespace;
    most of the Python Standard Library falls into this category.

    Open a SOCKS enabled socket. The parameters are the same as

    you must specify family=AF_INET, type=SOCK_STREAM and proto=0.

setproxy(proxytype, addr[, port[, rdns[, username[, password]]]])

        Sets the proxy to be used.
        proxytype -    The type of the proxy to be used. Three types
                are supported: PROXY_TYPE_SOCKS4 (including socks4a),
                PROXY_TYPE_SOCKS5 and PROXY_TYPE_HTTP
        addr -        The address of the server (IP or DNS).
        port -        The port of the server. Defaults to 1080 for SOCKS
                servers and 8080 for HTTP proxy servers.
        rdns -        Should DNS queries be preformed on the remote side
                (rather than the local side). The default is True.
                Note: This has no effect with SOCKS4 servers.
        username -    Username to authenticate with to the server.
                The default is no authentication.
        password -    Password to authenticate with to the server.
                Only relevant when username is also provided.
        headers -     Additional or modified headers for the proxy connect
        request.
