Low-level usage
***************

The library can also be used at a lower level, to extract a subset of data
from an mmCIF file. This can be done in either C or Python code.

For more information, see the :mod:`ihm.format` module, or the
`atom_reader.c <https://github.com/ihmwg/python-ihm/blob/main/examples/atom_reader.c>`_ or
`stream_parser.py <https://github.com/ihmwg/python-ihm/blob/main/examples/stream_parser.py>`_ examples.
