# 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. 
# 
# Examples:
#
# contrib/egcs_update -r egcs_latest_snapshot
# contrib/egcs_update -A
# contrib/egcs_update --nostdflags -P -r egcs_1_1_branch gcc/testsuite
