   7  *  DLL symbol extraction based on file format from alib (anthonyw.cjb.net).
   8  *
   9  *  Option processing shamelessly cadged from winebuild (www.winehq.com).
  10  *
  11  *  All the cool functionality (prototyping, call tracing, forwarding)
  12  *  relies on Patrik Stridvall's 'function_grep.pl' script to work.

  15  *  This article provides both a description and freely downloadble
  16  *  implementation, in source code form, of how to extract symbols
  17  *  from Win32 PE executables/DLL's.
  18  *
  19  *  http://www.kegel.com/mangle.html
  20  *  Gives information on the name mangling scheme used by MS compilers,
  21  *  used as the starting point for the code here. Contains a few
  22  *  mistakes and some incorrect assumptions, but the lists of types
  23  *  are pure gold.
