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 | |
9b14b81c | 18 | # reads --nostdflags, $UPDATE_OPTIONS as well as this parameter itself |
12acf3a9 AJ |
19 | # are omitted. |
20 | # | |
9d59f307 GP |
21 | # If the first parameter reads --patch, the second parameter is considered |
22 | # a patch file. | |

1b9f940b | 24 | # If the first parameter is --touch, no svn operation will be performed, |
94b82f2b AO |
25 | # only generated files that appear to be out of date in the local tree |
26 | # will be touched. | |
27 | # | |
28 | # If the first parameter is --list, a list of the generated files and | |
29 | # their dependencies will be printed; --help prints this message. | |
