Performer is a stand-alone Mudlet package that allows you to create and run pre-scripted commands in a timed sequence. The main purpose is to facilitate setpiece performances such as songs, rituals, dances, lessons, and other similar things.
I'd say it's in open beta with this, so feel free to send me/post bugs and ideas, and I may get to them eventually. Share as much as you want, and I can link you to my paypal if you love it so much you have to show it with money.

Open Mudlet -> Package Manager -> Install -> select Performer.zip
Enter "perf init"
"perf help" will give you the full list of commands. The aliases are a little basic, so you won't get debug info if you're far off the mark.
