An Example of If-then-else Format
---------------------------------

   Here is the output of `diff -DTWO lao tzu' (Note: Sample diff
Input, for the complete contents of the two files):

     #ifndef TWO
     The Way that can be told of is not the eternal Way;
     The name that can be named is not the eternal name.
     #endif /* not TWO */
     The Nameless is the origin of Heaven and Earth;
     #ifndef TWO
     The Named is the mother of all things.
     #else /* TWO */
     The named is the mother of all things.
     
     #endif /* TWO */
     Therefore let there always be non-being,
       so we may see their subtlety,
     And let there always be being,
       so we may see their outcome.
     The two are the same,
     But after they are produced,
       they have different names.
     #ifdef TWO
     They both may be called deep and profound.
     Deeper and more profound,
     The door of all subtleties!
     #endif /* TWO */
