[erlang-questions] no logger output using ?LOG macros in release

See if you are using any log formatters or handlers -- those may not be
direct dependencies of your application, and therefore do not get included
in the final release. You will need to add these dependencies to the
release independently so that they are present to run and handle output.

The rebar3 shell and other interactive modes can dynamically load libraries
from disk and won't show that little gotcha at all.
