+  The GCC toolchain in LPCXpresso can be used from the command line.  The
+  GDB configuration details for command line use are on Code Red Wiki:
+
+    http://support.code-red-tech.com/CodeRedWiki/UsingGDB
+
+  The driver for the LPC18xx and LPC43xx is (in my installation path):
+
+    /cygdrive/c/code_red/RedSuite_4.2.3_379/redsuite/bin/crt_emu_lpc18_43_nxp.exe
+
+  The 128K free version only supports the LPC-Link and RedProbe debug probes.
+  Other JTAG interfaces are supported in the full version.
