/* This stuff used to be in proxy.c too, but I split it off so BitlBee can
use other libraries (like libevent) to handle events. proxy.c is one very
nice piece of work from Gaim. It connects to a TCP server in the back-
ground and calls a callback function once the connection is ready to use.
This function (proxy_connect()) can be found in proxy.c. (It also
transparently handles HTTP/SOCKS proxies, when necessary.)
This file offers some extra event handling toys, which will be handled
by GLib or libevent. The advantage of using libevent is that it can use
more advanced I/O polling functions like epoll() in recent Linux
kernels. This should improve BitlBee's scalability. */
