Parameters
----------
ctx : Mapping, optional
The execution context for the shell (e.g. the globals namespace).
If none, this is computed by loading the rc files. If not None,
this no additional context is computed and this is used
directly.
shell_type : str, optional
The shell type to start, such as 'readline', 'prompt_toolkit',

config : str, optional
Path to configuration file.
rc : list of str, optional
Sequence of paths to run control files.
