Scheme RnRS metadata

This repo does fully automatic extraction from the unmodified TeX sources of the Scheme RnRS documents. If you run ./download.rkt and then ./parse.rkt you will obtain exactly the same result as I did.

download.rkt -- download and extract RnRS TeX files
parse.rkt -- parse metadata from extracted TeX files
r?rs/*.tex -- unmodified TeX sources extracted by download.rkt
r?rs-args.scm -- procedure and macro signatures extracted by parse.rkt
