Hey,

It looks like nng is packaged by Guix, can it be used?

You need to justify why the tests are disabled. Is it because there are
no tests, because some do not pass?

It would be better to use the new gexp based style. You can have a look
to the lldpd package above for an example.

You can omit the trailing #t.

This a commercial description. Something like: "Lightweight MQTT broker"
would be enough.

It does not really tell what this package does, what is a broker for
instance?

Could you please send an updated version :)? Don't hesitate to ask for
guidance if my comments are unclear.

Thanks,

Mathieu
