package log

/*

a simple way turn logging messages on and off. The gui config
window will let you enable & disable logging while your app is
running.

Example:

	log.Log(NETWARN, "socket connection failed to 127.0.0.1:8080")

In your package, register NETWARN:

	var NETWARN *log.LogFlag
	NETWARN = log.NewFlag("NETWARN", true, "go.wit.com/log", "log", "network warnings!")

		a = append([]any{"FLAG = NULL"}, a...)
		realPrintln(a...)
		return

	if !f.Get() {
		return
	}
	a = append([]any{f.short}, a...)
