"""Write model to files.
Write ``model`` to text files in a folder(directory) tree at ``model_path``.
Model attributes, such as its name and refs, are output in the file
named *_model.py*, directly under `model_path`.
For each space in the model, a text file is created with the same name
as the space with ".py" extension. The tree structure of the spaces
is represented by the tree of folders, i.e. child spaces
of a space is stored in a folder named the space.
Generated text files are Python pseudo-scripts, i.e. they are
syntactically correct but semantically not-correct Python scripts,
that can only be interpreted through :py:func:`~read_model` function.
Dynamic spaces and cells values are not stored.
For spaces and cells created
by :py:meth:`~modelx.core.space.UserSpace.new_space_from_excel` and
:py:meth:`~modelx.core.space.UserSpace.new_cells_from_excel`,
the source Excel files are copied into the same directory where
the text files for the spaces the methods are associated with are located.
Then when the model is read by :py:func:`~read_model` function,
the methods are invoked to create the spaces or cells.
Method :py:meth:`~modelx.core.model.Model.write` performs the same operation.
