+       NOTE:  One issue that I have seen with the NXHello example when
+       running as an NSH command is that it only works the first time.
+       So, after you run the 'nxhello' command one time, you will have to

+       This is clearly some issue with initializing, un-initializing, and
+       then re-initializing. If you want to fix this, patches are quite
+       welcome.

        support for the SLCDt can be enabled by making the following
