Nothing in the docs said that `parser-tools/yacc' is for LALR grammars
--- although I guess that it implied for most reader by the name "yacc",
but it doesn't hurt to say so explicitly. Meanwhile,
`parser-tools/cfg-parser' is useful for non-ambigious (non-LALR) grammars.
Also, from the style guide:
* Section Titles Should be In Titlecase, Like This
* Don't start a setence with an uncapitalized identifier.

The prior code constructed the location of nonterminal maches out of
the the state of the stream after parsing. This isn't right for a few
reasons:
1. It doesn't get starting location correctly.
2. It doesn't behave when the non-terminal production did not
actually consume tokens for its parse.
This patch modifies the parsers to also pass along a
"last-consumed-token"; it, along with a few other changes, provides
the parsers enough information to accurately construct the locations,
even when no tokens have been consumed during the parse. We
synthesize a sentinel last-consumed-token token to take location from
the head of the stream.

I started from tabs that are not on the beginning of lines, and in
several places I did further cleanings.
If you're worried about knowing who wrote some code, for example, if you
get to this commit in "git blame", then note that you can use the "-w"
flag in many git commands to ignore whitespaces. For example, to see
per-line authors, use "git blame -w <file>". Another example: to see
the (*much* smaller) non-whitespace changes in this (or any other)
commit, use "git log -p -w -1 <sha1>".

error raising procedure.

Macros and other tools that need syntax privilege used
`(current-code-inspector)' at the module top-level to try to
capture the right code inspector at load time. It's more
consistent to instead use the enclosing module's declaration-time
inspector, and `var-ref->mod-decl-insp' provides that. The
new function works only on references to anonymous variables,
which limits access to the inspector.
The real function name is longer, of course.

Started as fixing misindented definitions, then more indentations, then
a bunch of similar things (square brackets, huge spaces at end-of-lines,
etc).

added tutorial, racket categories
relabeled some other categories
normalized manual names: de-bolded, changed some names

Also, updates some of the mzlib files to point at `racket/*' libraries
rather than to `scheme/*' ones.

punctuations outside of the form, as it does with quote punctuations.
So things like this
#, @foo{...}
that required the space to make the @foo read as a scribble form are
now better written as
@#,foo{...}
This changes all such occurrences. (In case you see this change in
your files and are worried that there might be changes: I mechanically
verified that the result of `read'ing the modified files is identical
to the previous version.)
