 # OS Compatibility
 The Python .pyd files which wrap the CodeBase(tm) c4dll.dll and c4dll64.dll modules were compiled for Windows.  The 32-bit modules will run properly on either 32-bit or 64-bit Windows version 7 or later.  The 64-bit modules will run only on 64-bit Windows.  The COM functionality in ExcelComTools and DBFXLStools2 is specific to Microsoft Windows. As of October, 2018, the LibXL product, upon which the ExcelTools module is based (also required for the DBFXLStools2 module) is a Windows-specific component.  A 64-bit version of ExcelTools is not provided in this release, but may be added in the future.  The Python implementation you are running will determine which 32-bit or 64-bit version of this package you will be running.

 # Other Optional components
 The .PYD files (like CodeBasePYWrapper3X.pyd) provide native Python API access directly to the functions in c4dll.dll or c4dll64.dll without need for ctypes to access the raw .DLL C functions.  There is a significant speed and simplicity benefit from moving more program functionality directly into a compiled C program using the Python C API library, enabling direct access to the contained functions from the Python interpreter.  However, before we had developed the .PYD file(s) we developed "wrapper" DLLs that could be accessed directly by Python using ctypes.  We have not obsoleted these components, and they are found in the Comp_Wrappers and the Comp_Wrappers64 directories.  Full documentation is not provided for these components as we don't really see a need for them, but if you wish to make use of them, send us a GitHub message for more information.
