whats the deal with growl?

[SooTyLaD]

when i installed adium, it installed something called growl which seems to have got its way into a few programs...

it seems quite a good little program, so i was wondering if there is a way to see if there are other programs it can interract with? its got its claws into skype, transmission, and adium so far... i guess it just looks every now and then for compatible apps? is that right?

by the way, i have set it to not start on boot, but every time the bugger's there, anyone know why? something to do with GrowlMenu or is that summat different?

does it automatically link itself with Mail and Quicksilver and the like? i had those installed and Growl didn't have em in the programs list?

(also, does anyone know what the GrowlMenu is? its in my startup programs do i need it? i like as quick a startup as poss you see... there seems to be growl menu and summat else which i'm guessing is the main body of the app...)
