"""
The command line interface for ``mesh_part_prep`` allows you to run preperatory
steps needed to transform the output files generated by the `Triangle
<https://www.cs.cmu.edu/~quake/triangle.html>`_ program into `METIS
<http://glaros.dtc.umn.edu/gkhome/metis/metis/overview>`_ compatible input
files.

After installation, you can use::

    mesh_part_prep --help

    usage: mesh_part_prep [-h] [-l {DEBUG,INFO,WARNING,ERROR,CRITICAL}] mesh_dir

    positional arguments:
      mesh_dir              Path to the unpartioned mesh directory

    optional arguments:
      -h, --help            show this help message and exit
      -l {DEBUG,INFO,WARNING,ERROR,CRITICAL}, --log {DEBUG,INFO,WARNING,ERROR,CRITICAL}
                            Set the logging level


The only required argument is the path to the mesh::

    mesh_part_prep /some/path/goes/here

In this case, the level information is prepended to the ``aux3d.out`` file.
