By default, |

.I gendaymtx |
73 |

assumes the positive Y-axis points north such that the first sky patch |
74 |
+ |
is in the Y-axis direction on the horizon, the second patch is just |
75 |
+ |
west of that, and so on spiraling around to the final patch near the zenith. |

option rotates the sky the specified number of degrees counter-clockwise |
