Well, in hind site, the text kinda makes sence, but it is, like you said,
alittle unclear. The thing that confused me, was creating a GMainLoop.
The way the functions looked were similar to how threads look. It looks
like the loop that is returned is more then just the place holder that it
is. I am very poor at english, so I dont know how to clerify any farther.
sorry. anyway, thanks anyway. :)
