 * If you include this, you know what you are doing:
 *
 * Compile time debugging:
 * DP(("format", args)) prints debug to stderr
 * xDP(("format", args)) prints only if global debugging is on
 *
 * #define TINO_DP_all TINO_DP_ON
 * to enable global debugging
 *
 * #define TINO_DP_main TINO_DP_OFF
 * to disable global debugging (even yours)
 *
 * #define TINO_DP_<module> TINO_DP_ON
 * to activate partial debugging in a certain module
 * (this overrides other defines)
