DE		 26/* Hey look, some documentation [and in a place you expect to find it]!
27
28 The main reference for the pei format is "Microsoft Portable Executable
29 and Common Object File Format Specification 4.1". Get it if you need to
30 do some serious hacking on this code.
31
32 Another reference:
33 "Peering Inside the PE: A Tour of the Win32 Portable Executable
34 File Format", MSJ 1994, Volume 9.
35
36 The *sole* difference between the pe format and the pei format is that the
37 latter has an MSDOS 2.0 .exe header on the front that prints the message
38 "This app must be run under Windows." (or some such).
39 (FIXME: Whether that statement is *really* true or not is unknown.
40 Are there more subtle differences between pe and pei formats?
41 For now assume there aren't. If you find one, then for God sakes
42 document it here!)
43
44 The Microsoft docs use the word "image" instead of "executable" because
45 the former can also refer to a DLL (shared library). Confusion can arise
46 because the `i' in `pei' also refers to "image". The `pe' format can
47 also create images (i.e. executables), it's just that to run on a win32
48 system you need to use the pei format.
49
50 FIXME: Please add more docs here so the next poor fool that has to hack
51 on this code has a chance of getting something accomplished without
52 wasting too much time.
