[erlang-questions] Yaws and rebar3

By default, there's a kind of assumption in rebar3 that you'll use releases
to deploy your systems. If you do not, you can use the `rebar3 path' to
return a list of all paths, or use specific options:
--app Comma separated list of applications to return paths
--base Return the `base' path of the current profile.
--bin Return the `bin' path of the current profile.
--ebin Return all `ebin' paths of the current profile's
--lib Return the `lib' path of the current profile.
--priv Return the `priv' path of the current profile's
-s, --separator In case of multiple return paths, the separator
character to use to join them.
--src Return the `src' path of the current profile's
--rel Return the `rel' path of the current profile.
So for a command like yours, you could use something like -pa `rebar3 path
--separator=" -pa " to generate explicit path additions for all
dependencies, or use something like `erl -env ERL_LIBS `rebar3 path --lib`
and get mostly the same result. When working under a different profile
(i.e. tests with new dependencies) you can go `rebar3 as test path ...' and
get it to work.
The `path' task only relies on the 'app discovery' subtask, which basically
means that it relies only on the ability of rebar3 to read the shape of
your base repo to work. Using this task with `rebar3 get-deps' lets you use
rebar3 as a tool solely dedicated to fetching and upgrading dependencies,
without caring about the compilation or release phases if you were to use a
