[Zope] writing repozo messaging output to a file....

Would anyone know how to modify the repozo command to log output messages to a file? I realise that the 'v' flat displays messaging, however we're using a tool (VisualCron) which runs a series of commands and we are unable to view python output when this tool executes python commands... repozo -BvzQ -r /foo/backup -f /foo/Data.fs michael
