16 | # By default all command-line options are passed to `svn update` or `hg/git |
17 | # pull` in addition to $UPDATE_OPTIONS (defined below). If the first parameter | |

12acf3a9 AJ |
19 | # are omitted. |

21 | # If the first parameter reads --patch, the second parameter is considered |

28 | # If the first parameter is --list, a list of the generated files and | |
