// COMMON FILE: Common

// (c) 2010-2011, Deep IT, Uncle MiF

/*
	Customizes NSLog behavior for DEBUG session (-DDEBUG flag, or -DFORCE_LOGS)
	Activates only enabled mudules' logs or zones while debugging

	Include ColorLog after DIALog header to enable integration

	#define FORCE_SILENT_DEBUG
	to turn off Debug logs

	Add -DDONT_CHECK_FORMAT to C-Flags to disable format-related warnings while ColorLog integration
	but be aware abd double check security before!

	Install: simple add to the .pch file or to any .m files directly
	Make sure that the pch file (if used) is configured as GCC_PREFIX_HEADER

	Usage: NSLog(fmt,...), NSLogDebug(fmt,...), NSLogZone(zone,fmt,...), NSLogZoneDebug(zone,fmt,...)

	Be aware: internals use SIGUSR1 & SIGUSR2 as "once locks"
