         </p>
       </li>
     </ol><em>Note:</em> Files in "src-common" are shared. So editing
     "Common.java" in "Product1" will modify "Common.java" in "Product2".
     However they are compiled in the context of their respective projects. Two
     "Common.class" files will be generated; one for each project. If the two
     projects have different compiler options, then different errors could be
     reported on each "Common.java" file.
