# Reasons for excluding the messages (see pylint --list-msgs)
# W0142: we use *args **kwargs a lot
# W0403: don't issue warnings for relative imports
# C0301: we don't impose a limit on line length 
# C0111: we should always use docstrings but it's not that critical
# C0103: we don't have any convention about constant/variable/class names
# W0201: this is a common practice in extensions using signals
# W0613: this is a common practice in extensions for functions that catch signals
# W0702: this is valid when using log.exc()
# W0703: this is required when trying to get the exception (except Exception, e)
# W0704: we use empty except codes to ignore exceptions
# R0201: it could, but being a method sometimes improves code structure
# W0622: redefining builtins is not too bad for local scopes
