What does ‘Erlang/OTP’ mean here?  Is it like "make dist", or more like
"cargo publish", or "git tag v1.2.3"?

Greetings,

erlang-relx looks like some kind of tool that can be run and not a
library.  As such, does it belong in erlang.scm or package-
management.scm?  Does the input need to be propagated?  Can the
'erlang-' prefix be dropped?

Greetings,
Maxime.

The github repo says: „|relx| is a library used by rebar3“. Thus I'd 
keep the „erlang-“ prefix.

AFAIK: Like for Python, run-time dependencies of Erlang *libraries* need 
to be propagated. Erlang does not actually have a notion of „library“. 
It's more like Rust where all all dependent sources are expected to be 
available at build-time and then put into the „executable“. Basically 
this is statically linked, so only developers/package-builders are 
effected by this propagation.

Would be great if some experienced Erlang developer would show up and 
show a solution without needing to propagate.

OTP is a collection of middleware, libraries, and tools written in 
Erlang programming language (Wikipedia, 
https://en.wikipedia.org/wiki/Open_Telecom_Platform). AFAIU it's much 
like the Java run-time engine plus libraries.

So „Erlang/OTP” is a standing term in the Erlang and Elixir world. Thus 
I would keep it, expecting that Erlang developers understand this.

I can't explain what this library does — all I know is: it's a 
dependency of rebar3.
