+/** To generate a fatal compile-time error, you can use the pre-processor #error directive.
+ *
+ * @code
+ * #error "That shouldn't have happened!"
+ * @endcode
+ *
+ * If the compiler evaluates this line, it will report the error and stop the compile.
+ *
+ * For example, you could use this to check some user-defined compile-time variables:
+ *
+ * @code
+ * #define NUM_PORTS 7
+ * #if (NUM_PORTS > 4)
+ * #error "NUM_PORTS must be less than 4"
+ * #endif
+ * @endcode
+ *
+ * Reporting Run-Time Errors:
+ * To generate a fatal run-time error, you can use the mbed error() function.
+ *
+ * @code
+ * error("That shouldn't have happened!");
+ * @endcode
+ *
+ * If the mbed running the program executes this function, it will print the
+ * message via the USB serial port, and then die with the blue lights of death!
+ *
+ * The message can use printf-style formatting, so you can report variables in the
+ * message too. For example, you could use this to check a run-time condition:
+ *
+ * @code
+ * if(x >= 5) {
+ * error("expected x to be less than 5, but got %d", x);
+ * }
+ * #endcode
