+       Boards from Kickstarter project will not be available, however, until the first quarter of 2013.

+      MSYS has been modified, however, to interoperate in the Windows environment better than Cygwin and that may be of value to some users.

+    <p>
+      MSYS, however, cannot be used with the native Windows NuttX build because it will invoke the MSYS bash shell instead of the <code>CMD.exe</code> shell.
