/* Hey look, some documentation [and in a place you expect to find it]!

   The main reference for the pei format is "Microsoft Portable Executable
   and Common Object File Format Specification 4.1".  Get it if you need to
   do some serious hacking on this code.

   Another reference:
   "Peering Inside the PE: A Tour of the Win32 Portable Executable
   File Format", MSJ 1994, Volume 9.

   The *sole* difference between the pe format and the pei format is that the
   latter has an MSDOS 2.0 .exe header on the front that prints the message
   "This app must be run under Windows." (or some such).
   (FIXME: Whether that statement is *really* true or not is unknown.
   Are there more subtle differences between pe and pei formats?
   For now assume there aren't.  If you find one, then for God sakes
   document it here!)

   The Microsoft docs use the word "image" instead of "executable" because
   the former can also refer to a DLL (shared library).  Confusion can arise
   because the `i' in `pei' also refers to "image".  The `pe' format can
   also create images (i.e. executables), it's just that to run on a win32
   system you need to use the pei format.

   FIXME: Please add more docs here so the next poor fool that has to hack
   on this code has a chance of getting something accomplished without
   wasting too much time.  */
