;; The `elm` build usually calls out to itself via Template Haskell to compile
;; the `elm reactor` web app (which depends on additional Elm packages) and
;; embeds the static files into itself. The reactor isn't required to compile
;; Elm applications, so we want to skip it from the bootstrap package, but we
;; also want to be able to enable it once we can build it. We patch Elm to
;; instead look for the files on disk relative to the executable and to have
;; `elm reactor` exit with a useful error message if they aren't there.
