A while back the team at Comcast Interactive Media released LogBook, an AIR based application for logging messages from Flex applications. Today we have released an new swc that enables LogBook based logging for pure AS3 projects. The new swc is based on the CIM logging framework which is very similar to the one in Flex, but with no Flex dependencies. We have also released the asdocs for LogBook and the CIM Logging framework that can be found here. I have a more detailed entry on the CIM flash team blog here.
