[erlang-questions] Erlang package manager

I'm really concerned to see NPM and Maven presented as anything like
options regarding a package manager. On the one hand, there's a significant
difference between a build tool (Maven, Ant) and a package manager. On the
other, NPM relies on a feature of Node (using a tree to look up
dependencies at runtime, rather than a path) that isn't present in Erlang
(and, in my opinion, shouldn't be.) NPM is also weak in terms of deployment
(shrinkwrap is a big hassle) - and still very young (witness the change in
behavior regarding semver.)

If Erlang were to emulate another packaging system, I'd recommend looking
at rubygems and bundler in the Ruby community. It's biggest failing is that
the two projects were started separately, and that there's a reliance on
outside projects to deal with changes in VM for development.

The strongest reason I can see to build an Erlang centric PM is to support
Erlang's existing deployment behaviors i.e. releases.
