-      OpenOCD provides on-chip programming and debugging support with a layered
-      architecture of JTAG interface and TAP support, debug target support
-      (e.g. ARM, MIPS), and flash chip drivers (e.g. CFI, NAND, etc.).  Several
-      network interfaces are available for interactiving with OpenOCD: HTTP,
-      telnet, TCL, and GDB.  The GDB server enables OpenOCD to function as a
-      "remote target" for source-level debugging of embedded systems using the
-      GNU GDB program.
