The |

.I \-c |
| 57 |

option may be used to specify a color for the sky. |

The default sky color is |

.I "\-c 0.960 1.004 1.118". |

Similarly, the |

Alternatively, the |
| 72 |
|
.I \-s |
| 73 |

option may be used to exclude any direct solar component from the output. |

If there is a sun in the description, |
| 75 |

.I gendaymtx |
| 76 |

will include its contribution in the four nearest sky patches, |

distributing energy according to centroid proximity. |

The |

.I \-O1 |
| 108 |

option specifies that output should be total solar radiance rather |
| 109 |

than visible radiance. |

The |
| 111 |

.I \-h |
| 112 |

option prevents the output of the usual header information. |

Finally, the |
| 114 |
|
.I \-v |
| 115 |
|
option will enable verbose reporting, which is mostly useful for |

based on Jean-Jacques Delaunay's original gendaylit(1) implementation. |
