"Certain" in the "it just has to be true" sense... ;->  Apparently it
does not, which leads me to another, very simple question:

Why doesn't the following, placed in the source file, result in
debugging information being generated in the .beam file

-compile([export_all, debug_info]).

?  The export_all works as expected, but the debug_info option does not
seem to work.
