<bp-manager.log>.trace [object] [-regexp] [-re] ["substr"] ["substring"] [type] [-recursive]
Enable tracing of log messages matching the conditions specified by the type and substr arguments. The object argument of the command can be used to only trace log messages on a certain object. The substr argument is a string to match messages against. It is interpreted as a regular expression, as defined by the re module in Python, if the -regexp flag is specified.
Note that the log level must be set high enough for the message to be generated or it will not be found. If -recursive is used, not only the object, but the objects hierarchically below the object will be considered when adding the breakpoint.
