Hi Greg
Maybe I've got this wrong, but the way I understand it is that (apart from
an actual language) #lang can be used for a development environment that is
independent in some unique way. If I'm not mistaken even SICP is a #lang,
and some old Scheme books too, never mind the heaps of educational
languages inluded out of the box.
Since scmutils was initially directed at readers of SICM, I kind of imagine
(ultimate target) that such a reader could just grab DrRacket without
knowing much else about it, plonk a *#lang SICM* (or whatever the final
name is) and proceed with the exercises in the book(s) - since there's FDG
now, too. Tutorial material for both the books and any other general
mathematics / physics educational stuff could be released under the *#lang
SICM* label, too.
Hope I haven't got the wrong end of the stick.
Anyway, I've uploaded something now (with apologies ;) ) See my next post.
Regards
