Description: Overview
        --------
        This is a library for network oriented, coroutine based programming.
        
        *cogen*'s goal is to enable writing code in a seemingly synchronous and easy
        manner in the form of generators that yield calls and receive the result
        from that yield. These calls translate to asynchronous and fast os calls
        in *cogen*'s internals.
        
        Notable features
        ================
        
        * a WSGI server, HTTP1.1 compliant, with asynchronous extensions
        * epoll, kqueue, select, i/o completion ports, sendfile behind the scenes
        * a couple of useful classes for putting the coroutine to sleep, wait for
        signals, queues, timeouts etc.
        
        
        Quick introduction
        ==================
        A coroutine is just a generator wrapped in a helper class:
        
        ::
        
        from cogen.core.coroutines import coroutine
        
        @coroutine
        def mycoro(bla):
        result = yield <operation>
        result = yield <operation>
        
        
        * the `operation` instructs the scheduler what to do with the coroutine:
        suspend it till something happens, add another coro in the scheduler, raise
        a event and so on.
        * if a `operation` has a result associated then the yield will return that
        result (eg. a string or a (connection, address) tuple) otherwise it will
        return the operation instance.

        ::
        
        from cogen.core import sockets
        from cogen.core import schedulers
        from cogen.core.coroutines import coroutine
        
        @coroutine
        def server():
        srv = sockets.Socket()
        print type(srv)
        srv.bind(('localhost',777))
        srv.listen(10)
        while 1:
        print "Listening..."
        conn, addr = yield srv.accept()
        print "Connection from %s:%s" % addr
        m.add(handler, args=(conn, addr))
        
        @coroutine
        def handler(sock, addr):
        yield sock.write("WELCOME TO ECHO SERVER !\r\n")
        
        while 1:
        line = yield sock.readline(8192)
        if line.strip() == 'exit':
        yield sock.write("GOOD BYE")
        sock.close()
        return
        yield sock.write(line)
        
        m = schedulers.Scheduler()
        m.add(server)
        m.run()
