- a robust and flexible logging framework that can integrate with the |
|
PEP 282 logging module, or stand alone. It's simpler than the PEP 282 |
|
system for simple log configuration, and is configured on demand |
|
rather than "up front", and is thus more manageably configurable for |
|
large or complex applications consisting of components from diverse |
|
providers. |
