Library computing contrast ratios required by WCAG 2.0 (Python3 version)

 This package provides a Python library that calculates the contrast ratio of
 colors based on Web Content Accessibility Guidelines (WCAG) 2 standard,
 published by the Web Accessibility Initiative (WAI). The actual WCAG technical
 documents are created by the Accessibility Guidelines Working Group (AG WG),
 which are part of the WAI.
 .
 This library also provides some checking if contrast meets the required level.

 This package contains the Python 3 version of the library.
