# config/initializers/clear_logs.rb

# This snippet simply clears your logs when they are too large.
# Large logs mean looooong search in TextMate. You know it :)
# Every time you run rails server or rails console it checks log sizes 
# and clears the logs for you if necessary.

if Rails.env.development?
  MAX_LOG_SIZE = 2.megabytes
