   echo * Choose an Altera version to update your environment variables.

   echo *

   echo * Note:  Before making a selection, close any open Altera tools.

   echo *        After running this script, exit the shell from which it 

   echo *        was launched.  Only new environments will inherit the 

   echo *        new system environment settings.

   echo *

   echo * Note:  Some of these versions may not exist yet, or the paths 

   echo *        may not match your installation.  If you install to 

   echo *        non-standard locations, modify the paths at the top of 

   echo *        this batch file for each non-standard install path per 

   echo *        version.

   echo *

   echo *        For example, to modify the installation path information 

   echo *        for version 13.1, update 3 variables in this batch file: 

   echo *        Nios_13_1, Quartus_13_1, and IP_13_1.

   echo *

   echo * 1.     Version 13.1

   echo * 2.     Version 14.1

   echo * 3.     Do not make any changes
