6 | * |

7 | * It works by reading the input file into a linked list of lines |

8 | * and then performing sweeps on that list until all formatting is |
---|
9 | * complete. After the program is run, there is still a little |

10 | * clean up to be performed by hand. The following have to be fixed |

11 | * by hand: |
