##! This framework is intended to create an output and filtering path for
|
|
##! internal messages/warnings/errors. It should typically be loaded to
|
|
##! avoid Bro spewing internal messages to standard error and instead log
|
|
##! them to a file in a standard way. Note that this framework deals with
|
|
##! the handling of internally-generated reporter messages, for the
|
|
##! interface into actually creating reporter messages from the scripting
|
|
##! layer, use the built-in functions in :doc:`/scripts/base/reporter.bif`.
