If you look closely at the source, you will see code that appears to puts C code that includes itself. How and why? Perhaps it is in the DNA code of the code? Perhaps there are 23 reasons? :-)
This chromosome program synthesizes a double helix. The helix can also be compiled as a C program.
Enjoy DNA programming!
This program was inspired by Acme::DoubleHelix: http://search.cpan.org/~xern/Acme-DoubleHelix-0.01/
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
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.
