# GeneNetwork logger
#
# The standard python logging module is very good. This logger adds a
# few facilities on top of that. Main one being that it picks up
# settings for log levels (global and by module) and (potentially)
# offers some fine grained log levels for the standard levels.
#
# All behaviour is defined here. Global settings (defined in
# default_settings.py).
#
# To use logging and settings put this at the top of a module:
#
# import utility.logger
# logger = utility.logger.getLogger(__name__ )
#
# To override global behaviour set the LOG_LEVEL in default_settings.py
# or use an environment variable, e.g.
#
# env LOG_LEVEL=INFO ./bin/genenetwork2
#
# To override log level for a module replace that with, for example,
#
# import logging
# import utility.logger
# logger = utility.logger.getLogger(__name__,level=logging.DEBUG)
#
# We'll add more overrides soon.
