# 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.
|
|
#
|
|
# 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
