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.
20 # If the first parameter reads --patch, the second parameter is considered
21 # a patch file.
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24 # only generated files that appear to be out of date in the local tree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.
27 # If the first parameter is --list, a list of the generated files and
28 # their dependencies will be printed; --help prints this message.
30 # If the first parameter is --silent, this script prints nothing other
31 # than error messages; the second parameter is then interpreted as above.
33 # Examples:
35 # contrib/gcc_update -r 8712
36 # contrib/gcc_update --patch some-patch
37 # contrib/gcc_update --touch
38 # contrib/gcc_update --list
