"""
This inefficient module would parse the README.md in the initial version of
WTFPython, and enable me to categorize and reorder a hell lot of examples with
the help of the file `add_categories` (part of which is automatically
generated).

After the refactor, this module would not work now with necessary updates in
the code.
