- **BUGFIX** introduced in 0.5.0 when certain shells don't accept
      `[foo=bar, …]` parameters which should correctly be `[foo, bar]`
      Thanks to [@egze](https://github.com/egze) for submitting a patch.
    - Refactored `PathAgent` that holds configuration state for readability and
      more fashionable and extensible error messages. Extensible towards new
      generators.
    - Updated README to be more elaborative on how to install `wkhtmltopdf` and
      `chrome-headless-render-pdf`
