def parse(recent=True, class_set=set(), css_text=b''):
    """ It parses every eligible file in the project i.e. file type matches an element of settings.file_types.
    This ensures that from time to time unused CSS class selectors are removed from blowdry.css.

    **Order of Operations:**

    - Initialize settings.
    - Start performance timer.
    - Define File all file types/extensions to search for in project_directory
    - Get all files associated with defined file_types in project_directory
    - Get set of all defined classes
    - Filter class names only keeping classes that match the defined class encoding.
    - Build a set() of valid css properties. Some classes may be removed during cssutils validation.
    - Output the DRY CSS file. (user command option)
    - Output the Minified DRY CSS file. (user command option)

    **Depending on the settings this script generates the following:**

    - DRY CSS files
        - blowdry.css |sp| |sp| |sp| |sp| |sp| **human readable**
        - blowdry.min.css |sp| **minified**

    - Clashing Alias files (Encoded class selector aliases that are invalid and cannot be used because they clash.)
        - Markdown |sp| |sp| |sp| |sp| |sp| |sp| **Github**
        - HTML |sp| |sp| |sp| |sp| |sp| |sp| |sp| |sp| |sp| **Browser**
        - reStructuredText |sp| **Sphinx**

    - Property Alias File (Encoded class selector aliases that are valid and can be used to construct class selectors.)
        - Markdown |sp| |sp| |sp| |sp| |sp| |sp| **Github**
        - HTML |sp| |sp| |sp| |sp| |sp| |sp| |sp| |sp| |sp| **Browser**
        - reStructuredText |sp| **Sphinx**

    - Temporal Statistics

    **Note:** The default locations of these files can be overridden to suit your needs.

    **Directory assignments**
    ``project_directory`` -- Allows ``blowdrycss`` to know where the HTML project is located. It will only search
    the files in the directory specified here.
