/*
 * We define five functions for reporting errors, warnings and debug messages:
 * err()   - Fatal error.  Pass exit code followed by static string
 * errx()  - Fatal error.  Pass exit code, format string, one or more variables
 * warn()  - Warning. Pass static string
 * warnx() - Warning. Pass format string, one or more variables
 * dbg()   - Debug. Debug level to trigger, format string, one or more variables
 * notice() - Informational only via stderr, format string, one or more variables
