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

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25 # only generated files that appear to be out of date in the local tree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