The path to a file to be used as the base timestamp for prototype |

operations. If this is specified, all source file creation times |

are compared to the creation time of this file. Files created |

|
| 59 |

pathN The remainder of arguments to this command will be specified |
| 60 |
|
|
directly to pkgproto. These arguments specify which paths are to |
| 61 |
|
|
be included in the prototype. This can be specified as |
| 62 |
|
|
pathX=pathY to use a different prefix for files in the prototype |

than were present on the build system. |
