TFS2010 PostBuild template - logging

Where is the log files located when using the PostBuild activity in TFS 2010?

How can I increase the logging verbosity?

Build verbosity is set in the build definition and is then passed to the post FinalBuilder build activity. Setting this value to either Microsoft.TeamFoundation.Build.Workflow.BuildVerbosity.Diagnostic Or Microsoft.TeamFoundation.Build.Workflow.BuildVerbosity.Detailed will turn on verbose logging for the FinalBuilder run.

This will then write out all FinalBuilder messages to the TFS log.
