[erlang-questions] determining what erts version a .beam was compiled with

I believe there is a version attribute in the module_info tag 'compile'
telling at least the version of the compiler application used. I guess
this is actually more accurate since it must be for which beam object
code has been generated that is of interest. Not necessarily which
runtime system was used when compiling.
But I further guess that you must inspect this information using some
beam_lib function, because otherwise you must call the module_info
function and that means you have to load the module. But if it is
incompatible (younger than) to your runtime system at hand, that can
be difficult.

Subject: [erlang-questions] determining what erts version a .beam was compiled with

Does anyone know whether it is possible to tell by inspecting some .beam object code what erts vsn it was compiled on?
