Ah, quite interresting topic. Thanks to raise it!

I'm +1 on the idea to have "official binaries" but I really dislike
the idea to have to use build-couchdb for that. Or any system that use
rakes, ruby, python .... where we could just use erlang and unix
tools. It does the job but it's petty ugly (Jason, no offense,
build-couchdb does its job quite well).

I think to do the right job we could:

- adapt the build system to build proper elang release (using
reltools). We can wrap rebar for that since it's pretty efficient
these days and well supported (allows parralel builds, release buils
and clean updates) but this isn't really required, it can be perfectly
handled by autotools. (I think that using rebar would give us more
options though).  The advantage of using erlang release tools is that
we can cleanly manage the modules we need. You can manage templates,
so other distributors can adapt it to their system.

- Create a toolchain à la mozilla that would allows later to introduce
later cross-complication and start to support other platforms. They
are petty good for that and I think we can borrow a couple of ideas.

I would be really interested to work on such things. Also maybe with a
proper toolchain we could setup a build-bot that create nightly
releases and such.
