+ * @brief	IO redirection support
+ *
+ * This file adds re-direction support to the library for various
+ * projects. It can be configured in one of 3 ways - no redirection,
+ * redirection via a UART, or redirection via semihosting. If DEBUG
+ * is not defined, all printf statements will do nothing with the
+ * output being throw away. If DEBUG is defined, then the choice of
+ * output is selected by the DEBUG_SEMIHOSTING define. If the
+ * DEBUG_SEMIHOSTING is not defined, then output is redirected via
+ * the UART. If DEBUG_SEMIHOSTING is defined, then output will be
+ * attempted to be redirected via semihosting. If the UART method
+ * is used, then the Board_UARTPutChar and Board_UARTGetChar
+ * functions must be defined to be used by this driver and the UART
+ * must already be initialized to the correct settings.
