Unfortunately, these people have a trademark for the word "jade" referring to software, so we've been forced to change our name.
Fortunately, @davidglivar has kindly donated the name "pug" to us. I've claimed pug and pugjs everywhere I could think of so hopefully we shouldn't have any problems getting the name.
