Why does html5 boilerplate use Twipsy and Prototype when it builds jQuery code?

Question

So I just finished writing a single page with html5 boilerplate and everything is find with the dev code (the original one I just finished writing). Google Chrome and Firefox love it and display it well.

So I use the ant script ( ant build or ant text to skip jpeg/png optimization ) and browse to /publish/ to view it. And I got a javascript error :

Uncaught TypeError: Cannot read property 'Twipsy' of undefined

But the fact is I never used Twipsy or prototype, just jQuery ... so I run a javascript debug console and see in the generated javascript file a reference to Twipsy and Prototype. But I never use any of those in my code. So what's wrong ? and what can I do ?

Html5Boilerplate use a kind of very strong cache which actually keep the files you already delete in your project and always inline / include it in future build. You must delete publish and intermediate forlder to kepp your builder up to date.
