# Step 4: Generate C driver functions for ETK registration & NRPy+-generated kernels
# Now that we have constructed the basic C code kernels and the
# needed Einstein Toolkit ccl files, we next write the driver
# functions for registering BaikalETK within the Toolkit and the
# C code kernels. Each of these driver functions will be called
# directly from the thorn's schedule.ccl in the ETK.
# Step 4.a: First we call the functions in the `BaikalETK.BaikalETK_C_drivers_codegen`
# Python module) to store all needed driver C files to a Python dictionary,
