The code appears to be commented fairly well, but even without comments, $usage, and closing curlies, this script still has 575 lines (with ~100 lines of simple variable assignments). A "brief overview" might be difficult to achieve - what exactly do you need it for? If you're trying to learn something, it seems counterproductive to ask someone else to do the work for you. If you're just having trouble understanding some of the bits of this script, or you need to change something, you'll probably achieve more by asking more specific questions - what "challenges in understanding the flow" do you have?
