 * The synthesized helix just includes the original program at the head.
-  Do you see how `prog.c` determines whether it was invoked as a standalone program or included as a header file?
-  Note that it does not use any gcc extension such as `__INCLUDE_LEVEL__`.

 * The synthesized helix of course follows the base-pairing rules for DNA:
   A is bonding only to T, and C is bonding only to G.
