[erlang-questions] Running multiple beam files from an escript

[Roger Lipscombe]

"rebar3 escriptize" --
http://www.rebar3.org/docs/commands#section-escriptize -- lets you combine
multiple .erl files into a single escript. You can do the same with Elixir;
see
https://www.thegreatcodeadventure.com/executable-elixir-working-with-escripts/

Both of these take advantage of the fact that Erlang knows how to load BEAM
files from a .ZIP file, and that .ZIP files can have "garbage" on the
front. Said "garbage" being an entry point escript that invokes the main
module from the ZIP.

I experimented with it here: https://github.com/rlipscombe/escriptize --
but it's not maintained, so don't bother using it unless you need to
support dependencies with NIFs/ports in them.
