| # By default all command-line options are passed to `svn update` or `hg/git |
| # pull` in addition to $UPDATE_OPTIONS (defined below). If the first parameter |
| # reads --nostdflags, $UPDATE_OPTIONS as well as this parameter itself |
| # are omitted. |
| # |
| # If the first parameter reads --patch, the second parameter is considered |
| # a patch file. |
| # |
| # If the first parameter is --touch, no svn operation will be performed, |
| # only generated files that appear to be out of date in the local tree |
| # will be touched. |
| # |
| # If the first parameter is --list, a list of the generated files and |
| # their dependencies will be printed; --help prints this message. |
| # |
| # If the first parameter is --silent, this script prints nothing other |
| # than error messages; the second parameter is then interpreted as above. |
| # |
| # Examples: |
| # |
| # contrib/gcc_update -r 8712 |
| # contrib/gcc_update --patch some-patch |
| # contrib/gcc_update --touch |
