28 /* Hey look, some documentation [and in a place you expect to find it]!
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.
35 "Peering Inside the PE: A Tour of the Win32 Portable Executable
36 File Format", MSJ 1994, Volume 9.
38 The PE/PEI format is also used by .NET. ECMA-335 describes this:
40 "Standard ECMA-335 Common Language Infrastructure (CLI)", 6th Edition, June 2012.
42 This is also available at
43 https://www.ecma-international.org/publications/files/ECMA-ST/ECMA-335.pdf.
45 The *sole* difference between the pe format and the pei format is that the
46 latter has an MSDOS 2.0 .exe header on the front that prints the message
47 "This app must be run under Windows." (or some such).
48 (FIXME: Whether that statement is *really* true or not is unknown.
49 Are there more subtle differences between pe and pei formats?
50 For now assume there aren't. If you find one, then for God sakes
53 The Microsoft docs use the word "image" instead of "executable" because
54 the former can also refer to a DLL (shared library). Confusion can arise
55 because the `i' in `pei' also refers to "image". The `pe' format can
56 also create images (i.e. executables), it's just that to run on a win32
57 system you need to use the pei format.
59 FIXME: Please add more docs here so the next poor fool that has to hack
60 on this code has a chance of getting something accomplished without
61 wasting too much time. */
