It implements Conway's Game of Life by creating a DSL using the C preprocessor and printf. The output is a program (several initial boards are supplied to bootstrap) which is the input program to be compiled and run to create the next generation. This is the program for a second generation:
LIFE
L _ _ _ _ _
L _ _ O _ _
L _ _ _ O _
L _ O O O _
L _ _ _ _ _
GEN 2 STAT 328960
END
Each symbol like "LIFE" is a macro, the board is the program.
