+Build Instructions
+------------------
+
+1. Download RGMP from rgmp.svn.sourceforge.net:
+
+   cd <rgmp-dir>
+   
+   svn co https://rgmp.svn.sourceforge.net/svnroot/rgmp/trunk rgmp
+
+2. Configure NuttX.  For example, for the RGMP NSH configuration, do the
+   following:
+
+   cd <nuttx-dir>
+   cd tools
+   ./configure.sh rgmp/nsh
+   cd ..
+
+3. Edit Make.defs so that it can determine the include paths to the RGMP
+   installation directory.  I made this change to <nuttx-dir>/Make.defs:
+
+   --- configs/rgmp/nsh/Make.defs  2011-05-12 11:19:26.527273500 -0600

+
+NOTE: This needs to be better integrated with the RGMP build process. If
+you follow the above instructions, NuttX for RGMP will compile error-free
+but will fail at link time:
+
+  LD:  nuttx.exe
+  ld: cannot open linker script file /home/patacongo/projects/rgmp/rgmp/rtos/etc/x86.ld: No such file or directory
