+      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.
