Package Logging
===============

Description
-----------

The Standard or user specifig logging is carried out by the log.py module of the logging
package ka_uts_log using the configuration files **ka_std_log.yml** or **ka_usr_log.yml**
in the configuration directory **cfg** of the logging package **ka_uts_log**.
The Logging configuration of the logging package could be overriden by yaml files with
the same names in the configuration directory **cfg** of the application packages.

Log message types
-----------------

Logging defines log file path names for the following log message types: .

#. *debug*
#. *info*
#. *warning*
#. *error*
#. *critical*
