If you can live with distributing the core Erlang VM possibly
separately (not impossible in Windows land), you can definitely build
an escript archive, that contains modules and applications, and append
this to a suitably crafted .cmd file[1] for a single launchable
command.

You can pass most normal startup flags/arguments to the VM as well.

The escript archive can contain any required DLLs and successfully
call them too. This is very useful, but is it supported -- I've no
idea how it actually works.

There's brief notes on my recent (today) work for this with rebar
[2],[3] which should turn into a patch when I figure out a more clean
way of doing it. This was how erica.cmd was built.

A+
