Just a quick note that <https://github.com/schemedoc/packhack> now
produces JSON output in addition to the HTML that it previously made.
The JSON could be used as source material by a Scheme API server so
people can query the API for package information.

I also implemented a small caching framework in Racket so it will
automatically download whatever screen-scrape source material is missing
from its cache directory. Downloading each source document only once and
then caching them locally ought to be more polite to the people hosting
the package repositories.

I'd like to thank Frank for the excellent work in adding a RavenSc.com
scraper which I did not figure out how to do - and also for writing a
Makefile.
