New to Racket Scribble. I specialize in dumb questions.
I'm looking at using Scribble/text as a preprocessor for a lot of files
that happen to have a lot of @ signs in them. So either I need to escape

prone). Or, as I

The language you're seeing is mostly that of Racket *contracts*, even
though the implementation might not be using the Racket contract
software mechanism:

Can you use the escaping syntax that Scribble provides? Here's an example:
#lang scribble/base
@list|{ this is an example with @ signs in it. I can still
use @ by using it like this: |@tt{Hello world}, right?}|
Slightly larger example:

Let's try not to guess. Can you check your web server's error log. The
web server's error log is usually a lot more specific than the Internal
error that it sends to the browser. Apache often keeps it in the same
location as the regular server logs.

Hi all,
In DrRacket, why is there an extra empty string (`[]`between 0s) in
the list:`'( 0 0)`. This generates `([]0[][]0)`, instead of

Unfortunately, the question here is ambiguous. What are you trying to
do?
But you can move the defines outside the @list| form, as seen in
