+ This module is the main logger API. It contains functions that allow

+ events independently. To log events the logger
+ <seealso marker="#macros">macros</seealso> should be used. For instance,
+ to log a new error log event:</p>
+ <code>
+?LOG_ERROR("error happened because: ~p",[Reason]). %% With macro
+logger:error("error happened because: ~p",[Reason]). %% Without macro
+ </code>
+ <p>This log event will then be sent to the configured log handlers which
+ by default means that it will be printed to the console. If you want
+ your systems logs to be printed to a file instead of the console you
+ have to configure the default handler to do so. The simplest way is

+ <p>Logger can be configured either when the system starts through
