[racket] raco exe and collection path

I think the equivalent to DrRacket's Collection Paths setting might be
to use the PLTCOLLECTS environment variable? See:


Also there are a number of command-line flags; I'm not sure which
corresponds to exactly what you need:

$ racket -h
  -X <dir>, --collects <dir> : Main collects at <dir> (or "" disables all)
  -S <dir>, --search <dir> : More collects at <dir> (after main collects)
  -A <dir>, --addon <dir> : Addon directory at <dir>
  -R <paths>, --compiled <paths> : Set compiled-file search roots to <paths>
  -C <file>, --links <file> : User-specific collection links at <file>
