"""Python 2/3 compatible parsers for use in both Abaqus Python scripts and Turbo-Turtle Python 3 modules

Content *must* be compatible with Python 2 and 3. Content should be limited to those things necessary to construct the
CLI parser(s). Other content, such as project/package settings type variables, can be included to minimize the required
``sys.path`` modifications required in the Abaqus Python package/scripts. For now, that means this file does double duty
as the Abaqus Python package settings file and the parsers file.
