This package contains a late update to the Mindstorms drivers to address a
design flaw regarding communication with the AVR. The primary result is
that multiple motors may now reliably be controlled at once. A possible
conflict with configuring sensor power settings is also corrected. The
update also includes a more reliable way to command the Mindstorm NXT to
shut down.

To install this update, copy the following files to the "drivers"
subdirectory of the Mindstorms installation:

  nxt.ads
  nxt-avr.adb
  nxt-avr.ads
  nxt-avr_io.adb
  nxt-avr_io.ads
  nxt-buffers.adb

The "drivers" subdirectory is located under the GNAT tools installation
directory tree, specifically under the "mindstorms-nxt" subdirectory. By
default the installer will use a root of "\GNAT" so the typical full path
would be as follows:                                                                                      
                                                                                                                 
   C:\GNAT\2011\lib\mindstorms-nxt\drivers                                                                       
                                                                                                                 
Of course, your root location will be different if you do not take the
installer defaults.                       
                                                                                                                 
After installation, clean and then rebuild your applications so that the new
driver implementations are compiled and included in your executables.
