#! /bin/sh
#
# 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# only generated files that appear to be out of date in the local tree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
