3ca46d61 | 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 | |

175a12a4 | 19 | # are omitted. |

26a9ebc7 | 21 | # If the first parameter reads --patch, the second parameter is considered |
22 | # a patch file. | |
