+""" Set of methods used to retrieve access tokens by simulating the official VK application for Android.
+This is a Python port of the PHP module developed by Vodka2 to retrieve VK audio tokens. More info at https://github.com/vodka2/vk-audio-token
+This module, as a Python port, just tries to get the tokens by using the Official VK app's tokens. I did not implemented the Kate mobile functionality as it involves a lot of more work and is not giving any advantage over the official way.
+there are a lot of features pending to be applied. Hopefully later I can make it working more efficiently and OOP based.
