Set debug level
set_debug_level() - sets the debug level used by the driver's debug() macro
void set_debug_level( int | string level );
This efun is only available when the driver is compiled with -DDEBUG_MACRO. The purpose of this efun is to allow the amount and type of debugging information produced to be controlled from within the mud(while the driver is running). For more information, read the file debug.h which is included with the driver source.
