  28. /* Hey look, some documentation [and in a place you expect to find it]!
  29.  
  30.    The main reference for the pei format is "Microsoft Portable Executable
  31.    and Common Object File Format Specification 4.1".  Get it if you need to
  32.    do some serious hacking on this code.
  33.  
  34.    Another reference:
  35.    "Peering Inside the PE: A Tour of the Win32 Portable Executable
  36.    File Format", MSJ 1994, Volume 9.
  37.  
  38.    The *sole* difference between the pe format and the pei format is that the
  39.    latter has an MSDOS 2.0 .exe header on the front that prints the message
  40.    "This app must be run under Windows." (or some such).
  41.    (FIXME: Whether that statement is *really* true or not is unknown.
  42.    Are there more subtle differences between pe and pei formats?
  43.    For now assume there aren't.  If you find one, then for God sakes
  44.    document it here!)
  45.  
  46.    The Microsoft docs use the word "image" instead of "executable" because
  47.    the former can also refer to a DLL (shared library).  Confusion can arise
  48.    because the `i' in `pei' also refers to "image".  The `pe' format can
  49.    also create images (i.e. executables), it's just that to run on a win32
  50.    system you need to use the pei format.
  51.  
  52.    FIXME: Please add more docs here so the next poor fool that has to hack
  53.    on this code has a chance of getting something accomplished without
  54.    wasting too much time.  */
