SmartEiffel is now available through the symbolic link %%PREFIX%%/SmartEiffel.

Add %%PREFIX%%/SmartEiffel/bin to your path to be able to call 
the SmartEiffel compiler and its other utilities.

Make sure the environment variable SmartEiffel is defined and points to
%%PREFIX%%/SmartEiffel/sys/system.se.

One way to do this is to extend /etc/profile with the following line:

  SmartEiffel=%%PREFIX%%/SmartEiffel/sys/system.se; export SmartEiffel
