Thanks Cristian.
Man a full day away from my email and good things happen.
I should do this more often.

What I saw of R7RS-small in a quick skim suggests that (unless I missed
something hard) it could be done by an experienced programmer who was
new to Racket, or by someone like a smart CS undergrad who will put in
the hours to work through all the details.
You'll need some library procedures, s

Does the build that was created on Ubuntu not work? Since Racket loads
most libraries dynamically, our build should be especially portable.

Sorry I haven’t gotten around to posting this in the intervening week and a
half. Anybody who’s curious, please see

Hi Sam,
I probably have neither the skill, nor the time. But what the heck, I'll
start poking. In the end I probably won't get far, but I will have learned
a little Racket and a little Scheme... There are worse fates in this world
than that.
So, let's see... I start by copying the R5RS directory
I don't know -- it would certainly be jumping in at the deep end, but
it all depends on the user in question.

Hello,
I am a fairly new user of Scheme and Racket. My question is, now that
R7RS-small is out, when can I expect to see support added to Racket /
DrRacket? In other words, I would like to be able to type "#lang r7rs" in a
way analogous to how today I can enter "#lang r5rs" and "#lang r6rs".
Give
Right now, I think most Racketeers are focused on making Racket the
best Racket we can, rather than on Scheme, so I don't know of anyone
currently planning to work on this. However, the flexibility of Racket
means that it should be quite reasonable to adapt the existing R6RS
and R5RS implementation
