POE::Knee is a homophone of "Pony". We all like ponies. And wouldn't we love to race ponies? Well, that's what Acme::POE::Knee is for! . Using the POE event driven component architecture, you specify a distance the ponies must run, and a maximum delay before the pony will reach the next step. So, the bigger the delay, the bigger the distance between multiple ponies can be.
