I see what you mean about Debian's approach with the wrapper.

After some investigating I see that Clojure project's current approach
is different again to Debian. Their releases eg.
https://download.clojure.org/install/clojure-tools-1.9.0.XXX.tar.gz
include scripts `clj` and `clojure` which come from
https://github.com/clojure/brew-install. These scripts use functionality
from https://github.com/clojure/tools.deps.alpha/ to automatically
download any libraries you've declared a dependency on at runtime.

There will surely be a script that does this multi-repository build, but
I haven't found it yet.

Ben
