+
+    This configuration derives from the ostest configuration.  It has
+    been modified to us apps/examples/elf in order to test the ELF
+    loader.
+
+    NOTES:
+ 
+    1. This configuration uses the mconf-based configuration tool.  To
+       change this configuration using that tool, you should:
+
+       a. Build and install the mconf tool.  See nuttx/README.txt and
+          misc/tools/
+
+       b. Execute 'make menuconfig' in nuttx/ in order to start the
+          reconfiguration process.
+
+    2. Default toolchain:
+
+       CONFIG_STM32_CODESOURCERYW=y  : CodeSourcery under Windows
+
+    3. By default, this project assumes that you are *NOT* using the DFU
+       bootloader.
