- /* 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 PE/PEI format is also used by .NET. ECMA-335 describes this:
- "Standard ECMA-335 Common Language Infrastructure (CLI)", 6th Edition, June 2012.
- This is also available at
- https://www.ecma-international.org/publications/files/ECMA-ST/ECMA-335.pdf.
- 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. */
