| 4 # on treating generated files correctly, so that autoconf, gperf et | |
| 5 # al are not required for the ``end'' user. | |

| 15 # By default all command-line options are passed to `svn update` in | |
| 16 # addition to $UPDATE_OPTIONS (defined below). If the first parameter | |
| 17 # reads --nostdflags, $UPDATE_OPTIONS as well as this parameter itself | |
| 18 # are omitted. | |
| 19 # | |
| 20 # If the first parameter reads --patch, the second parameter is considered | |
| 21 # a patch file. | |
| 22 # | |
| 23 # If the first parameter is --touch, no svn operation will be performed, | |
| 24 # only generated files that appear to be out of date in the local tree | |
| 25 # will be touched. | |
| 26 # | |
| 27 # If the first parameter is --list, a list of the generated files and | |
| 28 # their dependencies will be printed; --help prints this message. | |
| 29 # | |
| 30 # If the first parameter is --silent, this script prints nothing other | |
| 31 # than error messages; the second parameter is then interpreted as above. | |
| 32 # | |
| 33 # Examples: | |
| 34 # | |
| 35 # contrib/gcc_update -r 8712 | |
| 36 # contrib/gcc_update --patch some-patch | |
| 37 # contrib/gcc_update --touch | |
| 38 # contrib/gcc_update --list | |
