+Subject: [PATCH] Allow building the python module with system openssl
+
+When building the python module and using the new
+GRPC_PYTHON_BUILD_SYSTEM_OPENSSL env variable, the third party
+boringssl code is not compiled. Instead, the openssl shared library
+installed on the system is used during runtime.
+This is useful for distributions who don't want to include code copies
+but use shared libraries instead.
