# 8th Fetcher — Парсер Восьмого ветра
## Godville game profiles parser
Dependencies ruled by [dep](https://github.com/golang/dep).
This parser designed to be companion of [8th Wind](https://wind8.ru) site engine. This program parses profiles and sends them to API endpoint of wind8 site engine.
You can use this parser for your own purposes, but you will do it at your own risk. I'm not responsible for anyone who violates Godville game rules using this software.
This software created for demonstation purposes only.
## Парсер профилей игры Годвилль
Зависимости управляются при помощи [dep](https://github.com/golang/dep).
Этот парсер создан для работы с сайтом [Восьмой ветер](https://wind8.ru). Приложение ``wind8_fetcher`` парсит профили Годвилля и отдаёт данные по API движку сайта.
Вы можете использовать эту программу для своих личных задач, но делайте это на свой страх и риск. Я не несу ответственности за каждого, кто нарушит правиля Годвилля с помощью этой программы.
Данная программа создана исключительно в ознакомительных целях.
