+/* 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.
