"""Messages and logging for bazaar-ng
18
Messages are sent out through the Python logging library.
20
They can be sent to two places: to stderr, and to ~/.bzr.log.
22
~/.bzr.log gets all messages, and tracebacks of all uncaught
25
Normally stderr only gets messages of level INFO and higher, and gets
26
only a summary of exceptions, not the traceback.
22
Nothing is actually logged unless you call bzrlib.open_tracefile().
30
# TODO: in debug mode, stderr should get full tracebacks and also
31
# debug messages. (Is this really needed?)
33
# TODO: When running the test suites, we should add an additional
34
# logger that sends messages into the test log file.
