+One can override the following variables :
+
+LOG_LEVEL : The log level, from 0 to 5.
+A Log level n implies all logs from 0 to n.
+LOG_LEVEL MUST BE OVERRIDEN !!!!!
+
+
+LOG_NONE = 0            => No log output
+LOG_CRITICAL = 1        => Critical problems (data consistency, module integrity, ...)
+LOG_ERROR = 2           => Error (runtime exceptions, ...)
+LOG_WARNING = 3         => Warning (non-blocking exceptions, ...)
+LOG_NOTICE = 4          => Notices (Special conditions, ...)
+LOG_DEBUG = 5           => Debug (Debugging information)
+
+
+LOG_PROCESSOR : A dictionnary holding, for each key, the data processor.
+A data processor is a function that takes only one parameter : the data to print.
+Default : LogFile for all keys.
