 Module Name:

    InjectDll.cpp

 Abstract:

    This Shim inject given DLLs on the command line at
    SHIM_STATIC_DLLS_INITIALIZED so that if people try to load
    dynamic library in their own DllInit, no dependencies occur
    because the dynamic libraries are in place.

    One problem was: Visio 2000 call LoadLibrary(VBE6.DLL) which
    (shame on us) loads MSI.DLL in its DllInit.
