 If you are running on another Unix-like operating system (OSX, etc) then
 you may wish to build the native libraries.  They are not strictly necessary
 but having them available suppresses a runtime warning and enables Accumulo
-to run faster. Unpack the accumulo-native tarball in the $ACCUMULO_HOME/lib 
-directory. Change to the accumulo-native directory in the current directory
-and issue `make`. Copy the resulting 'libaccumulo' library into the

+to run faster. You can execute the following script to automatically unpack
+and install the native library. Be sure to have a JDK and a C++ compiler 
+installed with the JAVA_HOME environment variable set.
+
+  $ ./bin/build_native_library.sh
+
+Alternatively, you can manually unpack the accumulo-native tarball in the 
+$ACCUMULO_HOME/lib directory. Change to the accumulo-native directory in 
+the current directory and issue `make`. Then, copy the resulting 'libaccumulo' 
+library into the $ACCUMULO_HOME/lib/native/map.
 
   $ mkdir -p $ACCUMULO_HOME/lib/native/map
   $ cp libaccumulo.* $ACCUMULO_HOME/lib/native/map

 If you want to build the debian release, use the command "mvn package -Pdeb" to 
 generate the .deb files in the target/ directory. Please follow the steps at
