# Logging settings for django projects, works with django 1.5+
# If DEBUG=True, all logs (including django logs) will be
# written to console and to debug_file.
# If DEBUG=False, logs with level INFO or higher will be
# saved to production_file.
# Logging usage:

# import logging
# logger = logging.getLogger(__name__)
# logger.info("Log this message")

"""
Settings for root logger.
Log messages will be printed to console and also to log file (rotated, with
specified size). All log messages from used libraries will be also handled.

Three approaches for defining logging settings are used:
1. using logging classes directly (py25+, py30+)
2. using fileConfig (py26+, py30+)
3. using dictConfig (py27+, py32+)
Choose any variant as you like, but keep in mind python versions, that

python vkcom_audio_download.py

Скрипт проверяет сохраненный access_token. Если его нет или срок истек,
то открывается страница в браузере с запросом на доступ к аккаунту.
