 = HTTP Router
 
-== Introduction
-
-When I wrote Usher, I made a few compromises in design that I wasn't totally happy with. More and more features got added to it, and eventually, it became harder to maintain. I took a few moments to work in Node.js, and wrote a router there called Sherpa, which I was happier with. But I felt that by losing more abstraction, and tackling just the problem of HTTP routing, I could come up with something even better.
-
-== Warning
-
-This is very new code. Lots of stuff probably doesn't work right. I will likely never support all the features I had in Usher. Documentation is super-sparse.

 == Features
 
 * Supports variables, and globbing, both named and unnamed.
