In the late 90s, all of us had a FluxKit image on our laptops that would boot PLT Scheme on the raw machine. Matthew, with help from the Flux people, put it together in a relatively short time. I am sure more could have done with that, but we went in different directions. At Strange Loop I

If we add up the "Racket" and "Scheme" numbers (the latter being, I suspect, mostly Racket), the total is pretty close to Ruby. I find that amusing. :) Actually, I'm curious what the numbers look like if you count "PLT Scheme" towards Racket. Vincent On Wed, 24 Feb 2016 11:06:51 -0600, Brian

From the Scribble documentation for a third-party package, how do I link to: * a core Racket document; and * the documentation for a third-party package from the catalog? Ideally, in both cases it would go to locally-installed documentation, if available, and fallback to "docs.racket-lang.org"
