b9550bfb | 3 | # Update a local CVS tree from the GCC repository, with an emphasis |
d9ddcc6a | 4 | # on treating generated files correctly, so that autoconf, gperf et |
f717c7e4 GP |
5 | # al are not required for the ``end'' user. |

9b14b81c GP |
7 | # By default all command-line options are passed to `cvs update` in |
8 | # addition to $UPDATE_OPTIONS (defined below). If the first parameter | |
9 | # reads --nostdflags, $UPDATE_OPTIONS as well as this parameter itself | |
12acf3a9 AJ |
10 | # are omitted. |
11 | # | |
9d59f307 GP |
12 | # If the first parameter reads --patch, the second parameter is considered |
13 | # a patch file. | |
12acf3a9 | 14 | # |
94b82f2b AO |
15 | # If the first parameter is --touch, no cvs operation will be performed, |
16 | # only generated files that appear to be out of date in the local tree | |
17 | # will be touched. | |
18 | # | |
19 | # If the first parameter is --list, a list of the generated files and | |
20 | # their dependencies will be printed; --help prints this message. | |
21 | # | |
2d072788 ZW |
22 | # If the first parameter is --silent, this script prints nothing other |
23 | # than error messages; the second parameter is then interpreted as above. | |
