Hi all,
re: Racket 6.5, prebuilt Linux x86_64 distribution
on Centos 6.8
Had a crash in one of my headless webserver/database applications. The
application itself is 100% Racket (no FFI libs), using the webserver
and db modules heavily. The Racket install is default with no added

I am trying to use Scribble to produce nicely-formatted tables of data.
Some of these tables are both longer and wider than one printed page.
I would like to handle this similarly to typical spreadsheet programs,
which automatically create page breaks. Ideally, I'd also like to repeat

Metadata is my main concern, and it's important in GIS and could be improved
upon there -- IMHO. I get the impression from my research that the future of
serious metadata is rooted in type theory and graph databasing, i.e, being able

Yes: it's standard for Racket documentation.
What would be the novel aspect(s) of your GIS app?

For making-TIkz like diagrams check out Jens Axel Søgaard's MetaPict
library. It has as an explicit goal "to narrow the gap between Scribble and
