-// You do not need to edit this part of file unless you are changing the core
-// pytorch export abstractions.
-//
-// This part defines the C10 core export and import macros. This is controlled
-// by whether we are building shared libraries or not, which is determined
-// during build time and codified in c10/core/cmake_macros.h.
-// When the library is built as a shared lib, EXPORT and IMPORT will contain
-// visibility attributes. If it is being built as a static lib, then EXPORT
-// and IMPORT basically have no effect.
-
-// As a rule of thumb, you should almost NEVER mix static and shared builds for
-// libraries that depend on c10. AKA, if c10 is built as a static library, we
-// recommend everything dependent on c10 to be built statically. If c10 is built
-// as a shared library, everything dependent on it should be built as shared. In
-// the PyTorch project, all native libraries shall use the macro
-// C10_BUILD_SHARED_LIB to check whether pytorch is building shared or static
-// libraries.
-
-// For build systems that do not directly depend on CMake and directly build
-// from the source directory (such as Buck), one may not have a cmake_macros.h
-// file at all. In this case, the build system is responsible for providing
-// correct macro definitions corresponding to the cmake_macros.h.in file.
-//
-// In such scenarios, one should define the macro
-//     C10_USING_CUSTOM_GENERATED_MACROS
-// to inform this header that it does not need to include the cmake_macros.h
-// file.
