That makes sense, but now I realize that I need to know previous
command lines, if you have them.

By the time you ran `raco setup carali', the installation had become
confused about "scribblings/main/user\search.scrbl" and
"scribblings\main\user\search.scrbl" being the same document (i.e.,
there's some path-normalization problem).

That looks like a fine organization overall.

Instead of

 (module <filename> racket
   ...)

most of us use just

 #lang racket

Hopefully the `#lang racket' form is more suggestive: It indicates that
the module is implemented in the `racket' language, as opposed to
`typed/racket' or `scribble/manual' or any number of other languages.

Putting code into module is definitely the right approach.

Yes, `raco setup' and other tools consult "info.rkt" for
meta-information about a library collection, such as how to build its
documentation.

No, "main.rkt" is special only in that it enables a shorthand. Use it
when a main library makes sense for a collection, so that `(require
carali)' can be used as a shorthand for `(require carali/main)'.
