| # Update a local CVS tree from the GCC repository, with an emphasis |
| # on treating generated files correctly, so that autoconf, gperf et |
| # al are not required for the ``end'' user. |
| # |
| # By default all command-line options are passed to `cvs update` 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 cvs 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| # only generated files that appear to be out of date in the local tree |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. |
| # |
| # Examples: |
| # |
| # contrib/gcc_update -r gcc_latest_snapshot |
| # contrib/gcc_update -A |
| # contrib/gcc_update --nostdflags -P -r gcc-2_95-branch gcc/testsuite |
| # contrib/gcc_update --patch some-patch |
| # contrib/gcc_update --touch |
| # contrib/gcc_update --list |
