-/* FreezeDLLMain.cpp
-
-This is a DLLMain suitable for frozen applications/DLLs on
-a Windows platform.
-
-The general problem is that many Python extension modules may define
-DLL main functions, but when statically linked together to form
-a frozen application, this DLLMain symbol exists multiple times.
-
-The solution is:
-* Each module checks for a frozen build, and if so, defines its DLLMain
-  function as "__declspec(dllexport) DllMain%module%"
-  (eg, DllMainpythoncom, or DllMainpywintypes)
-
-* The frozen .EXE/.DLL links against this module, which provides
-  the single DllMain.
-
-* This DllMain attempts to locate and call the DllMain for each
-  of the extension modules.
-
-* This code also has hooks to "simulate" DllMain when used from
-  a frozen .EXE.
-
-At this stage, there is a static table of "possibly embedded modules".
-This should change to something better, but it will work OK for now.
-
-Note that this scheme does not handle dependencies in the order
-of DllMain calls - except it does call pywintypes first :-)
-
-As an example of how an extension module with a DllMain should be
-changed, here is a snippet from the pythoncom extension module.
