[erlang-questions] Beams dependency tool

[Maxim Treskin]

Hello

How I can get list of beams which used by my application?
I need smallest system to deploy on embedded hardware (ARM) and do not want to 
take unused beams. I know that there may be implicit module usage, like

Mod = list_to_atom("somemodule"),
Mod:somefun()

but it is not big problem.
So, is there any tool for this? May be some actions with dialyzer?

Thank you
