I was updating my copy of the PBE2 repo and looked at the site for PBE2.

There are quite a number of tex files in the repo that have no PDF rendition.

Is there any kind of already made script I can use to get them all rendered like that?

I am interested in getting the material from not yet released files in a readable format.

As I have been working a bit on sound, I think I could also contribute something to a chapter on that subject.

Are there any rules on how to write for that?
