- Log path's are generated in the scripting land
now. The default Log stream ID to path string
mapping works like this:
- Notice::LOG -> "notice"
- Notice::POLICY_LOG -> "notice_policy"
- TestModule::LOG -> "test_module"
- Logging streams updated across all of the shipped
scripts to be more user friendly. Instead of
the logging stream ID HTTP::HTTP, we now have
HTTP::LOG, etc.
- The priorities on some bro_init handlers have
been adjusted to make the process of applying
filters or disabling streams easier for users.

##! This script lets Barnyard2 integrate with Bro. It receives alerts from

|

##! and derive new notices from the alerts.
