[racket] Current advice on making a 'script'

Does the PLTCOLLECTS environment variable help here? I mean, as an
alternative to inlining all of the required modules in the script
itself or using `raco link` to set up local packages? Or have I
misunderstood the problem?

Hence rewriting the various (require "foo.rkt") and concatenating them in dependency order.  It's not pretty (I can just sense, and indeed share, Jay's distaste for sed-ding a Racket source file, from here!), but it seems robust, and has the straightforwardness of a single-file 'executable', without the hammer-to-crack-a-nut of 'raco exe' (though disk space is cheap, of course; and in my case it's only 6MB, so what's the odds....).
