"""Medical Image Registration ToolKit

This is the Python package of MIRTK. It can be used to execute the MIRTK
commands as subprocesses within a image processing pipeline written in Python.
Moreover, some MIRTK modules may provide loadable Python modules.

To call a MIRTK command, either use the functions of the mirtk.subprocess module,
or simply execute a command using mirtk.<command>(args, option=value).
This will invoke the mirtk.subprocess.run function with name=<command> and
the provided positional and keyword arguments.
