This program can be used to make OS packages for an Erlang application bundled as an OTP release.
Create a pkgx.config in the root of your project. Look at the
pkgx.config.sample file for instpiration. Also, make sure that
you're all set with generating a release using rebar3.
Typical workflow scenario:
$> rebar3 release
$> pkgx deb
Now, you have a *.deb file in your _build/prod/rel/ directory
which holds the Erlang release and can be easily installed on a target
system.
The service will automatically start (using an init.d script), and
runs under a new user account. Log files are found in
/var/log/(package). A default, empty, config file is created in
/etc/(package)/(package).config, from which application environment
variables are read from.
