"""
Scan the api files in ``api_files`` and emit
the relevant ``api_*.h`` and ``api_*.cpp`` files
for the api modules into the ``api_output_dir``
directory.
Scan the api files in ``api_files`` and emit the relevant API files into
the output directories specified. If an output directory is set to ``None``
then the files for that language binding or module are not emitted.
For the remaining arguments, if said argument is
not ``None`` the relevant files for that language
binding will be emitted to the specified directory.
The reason for this function interface is:
* The CMake build system needs to control where
files are emitted.
* The CMake build system needs to be able to choose
which API files are emitted.
* This function should be as decoupled from the Python
build system as much as possible but it must be possible
for the Python build system code to use this function.
Therefore we:
* Do not use the ``mk_util.is_*_enabled()`` functions
to determine if certain files should be or should not be emitted.
* Do not use the components declared in the Python build system
to determine the output directory paths.
