module Innate
# Innate only provides logging via stdlib Logger to avoid bloat and
# dependencies, you may specify multiple loggers in the Log instance of LogHub
# to accomendate your needs, by default we log to $stderr to be compatible with
# CGI.
#
# Please read the documentation of logger.rb (or even better, its source) to
# get a feeling of how to use it correctly within Innate
#
# A few shortcuts:
#
# 1. Create logger for stderr/stdout
# logger = Logger.new($stdout)
# logger = Logger.new($stderr)
#
# 2. Create logger for a file
#
# logger = Logger.new('test.log')
#
# 3. Create logger for file object
#
# file = File.open('test.log', 'a+')
# logger = Logger.new(file)
#
# 4. Create logger with rotation on specified file size
#
# # 10 files history, 5 MB each
# logger = Logger.new('test.log', 10, (5 << 20))
#
# # 100 files history, 1 MB each
# logger = Logger.new('test.log', 100, (1 << 20))
#
# 5. Create a logger which ages logfiles daily/weekly/monthly
#
# logger = Logger.new('test.log', 'daily')
# logger = Logger.new('test.log', 'weekly')
# logger = Logger.new('test.log', 'monthly')
