This folder contains export definiton files (*.def) for win32 .dll to DMD interfacing. Use in the same way you would use an implib for linking into your application:
dmd -ofmyprogram.exe myprog.obj win32lib.def
You can use a .def to create an import .lib (using DM's implib):
implib shell32.lib shell32.def
(using DM's implib) If you just need all of the dll, simply pass the dll
implib shell32.lib shell32.dll
Examples of .def files:
