Well, I'll need to find the thread in the emacs-devel mailing list in
which people discuss the conversions of the source files to lexical

emacs-version its brand of linux provides?

By the way:
This one of the moments I get stumped. The example for the
explanation is contradictionary - what shoult the student do?

Cheers
