        =================

        - create_time

            The file created time. It will be automatically set when you create
            a new file if you use it.

        - author

            The file creator.

            FileHeader will set it automatically. If it's in
            a git repository and the `user.name` has been set, `autor`
            will set to `user.name`, otherwise it will be set to current
            system user.

            Can be set custom.

        - last_modified_by

            The file last modified by who? It is specially useful when
            cooperation programming.

            FileHeader will set it automatically. If it's in
            a git repository and the `user.name` has been set, `autor`
            will set to `user.name`, otherwise it will be set to current
            system logined user.

            Can be set custom.

        - last_modified_time

            The file last modified time.

            FileHeader will set it automatically when you save the file.

            Can't be set custom.

        - file_path

            The absolute path of the current file.

            FileHeader will update it automatically when you change it.

            Can't be set custom.

        - file_name

            The name of current file with extension.

            FileHeader will update it automatically when you change it.

            Can't be set custom.

        - file_name_without_extension

            The name of current file without extension.

            FileHeader will update it automatically when you change it.

            Can't be set custom.

        - project_name

I posted the Python template I use alongside this file when I am creating MIT licensed python code: https://gist.github.com/mateor/9f9e075819d5572b7b2770ac4c1209bb

A new file looks like:

  # coding=utf-8
  # The MIT License (MIT)
  # Copyright (c) 2016 mateor

  from __future__ import (absolute_import, division, generators, nested_scopes, print_function,
                          unicode_literals, with_statement)

It treats the __init__.py as a special file - in order to allow all new empty files to get the header but skip the __init__files, which are best left empty.
