Hi Michael,

Thanks for your pointer to escript, I'm not familiar with it, I'll
look at its possible use on Android since it mentions the support of
relocatable installations indeed. Android has many restrictions
compared to typical Unix systems, so it may not fully work as-is, I'll
see how far I can get.

Going back to my original goal, I'm still focusing on the typical
Erlang runtime installation and I would really like to make it more
"robust" for Android, in particular the erl program (which is a shell
script), as it has been working perfectly fine up to Android 9
included (until the newer Android restrictions I've described).
