#
# Update a local CVS tree from the egcs repository, with an emphasis
# on treating generated files correctly, so that autoconf, bison 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# only generated files that appear to be out of date in the local tree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/egcs_update -r egcs_latest_snapshot
# contrib/egcs_update -A
# contrib/egcs_update --nostdflags -P -r egcs_1_1_branch gcc/testsuite
# contrib/egcs_update --patch some-patch
# contrib/egcs_update --touch
# contrib/egcs_update --list
