I'll adjust the docs to clarify that language info was a failed idea

Ah, I misread the your original question as can an installed package
have fewer files?.
For rendering a document independent of a package installation, I think
we're pretty close to a good answer with
#lang racket
(require scribble/render
(prefix-in html: scribble/html-render)
No, there's not already a way in place.
Is it a question of file count or file sizes?
There are many goals and constraints that go into that layout, so
removing any individual file is difficult.
I think the size could be reduced a lot, though. For example, the
manual-fonts.css file doesn't
Are you looking for `manual-doc-style` to add to your document's main
part? Or do you need more information about applying a style from the
outside of a document whose source you can't modify?

Yes, that's strange behavior.
Just to be clear, the reader works at the layer of characters, which
means that the content of a #... literal is expressed in terms of
characters.
The intent is that characters in the Unicode range 0-255 represent the
corresponding byte value in the byte string ---
-get p1) ; = 'ready
(place-channel-put p1 v1)
(time (place-channel-get p1)))
That way, `v1` doesn't sit in the message channel long enough to cause
a problem.

This does seem extremely slow. A place-message send must copy the
vector to send it as a message, but the copy shouldn't take so long.
I'll investigate further.
Meanwhile, an option in this case might be to created a shared
flvector, which can be passed directly (i.e., without copying) to
another
Yes, it's a problem with yesterday's snapshot from Utah, and the most
recent one failed for unrelated reasons. I've kick off a new snapshot,
so it should be available in about 3 hours.
If you can tolerate errors provoked by bad snapshots, then I think
building against the snapshot is a good
Yes, the `dc` pict constructor provides a bridge between `racket/draw`
and picts:

(+ x 100) (+ y 100)))
100 100))

I can see why you might want or expect '(4) below, and it turns out
that changing `delay` to `delay/thread` makes the result '(4) instead
of '(5).
We could extract that facet of `delay/thread` (without the concurrency)
as

The two-subform case of `definer` uses the overall form, `stx`, to
provide a content for the introduced `arg-id` binding. So, when you use
the two-subform variant directly in some context, then you can see the
`arg-id` binding
It looks like kqueue() is broken for FIFOs on Mac OS X. See the
enclosed kqueue_fifo.c. Unless I'm confused (a review of the enclosed
program would be welcome), adding a kqueue event to watch for FIFO
input disables an event that watches for FIFO output space, or
something like that.
