""" 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.

the files in the directory specified here.
