+# By RidgeRun Inc.
+#
+# Description:
+#   Create a system containing a copy of the compressed vmlinux kernel.
+#   The system knows how to decompress the contained kernel and then
+#   jump to it resulting in a linux kernel boot.
+#
+#   The system comes in three forms:
+#
+#       1. - ramsys - 
+#          to be loaded into ram then run. When run
+#          it decompresses the kernel housed in its internal
+#          data structures and then jumps to the image which
+#          results in a linux kernel boot.
+#
+#       2. - flashsys - 
+#          to be loaded into ram so that it can be
+#          burned into the onboard flash. Then the board jumpers
+#          can be switched so that the next power cycle caused
+#          the system in flash to run which then proceeds as
+#          described by #1 above.
+#          Note: burner.srec is the utility that will allow
+#          the user to get this image into flash.
+#
+#       3. - flashsys2 - 
+#          to be loaded into ram so that it can be
+#          burned into the onboard flash. Then on each power
+#          cycle when the standard PMON prompt is presented 
+#          the user can type `call 0xbf000000` to invoke
+#          the system in flash which then proceeds as
+#          described by #1 above.
+#          Note: burner.srec is the utility that will allow
+#          the user to get this image into flash.
+#
+#       4. - burner.srec -
+#          related to #2 and #3 above.
