+# This script adjusts the copyright notices at the top of source files

+#
+# Copyright XXXX-YYYY Free Software Foundation, Inc.
+#
+# It doesn't change code that is known to be maintained elsewhere or
+# that carries a non-FSF copyright.
+#
+# Pass --this-year to the script if you want it to add the current year
+# to all applicable notices. Pass --quilt if you are using quilt and
+# want files to be added to the quilt before being changed.
+#
+# By default the script will update all directories for which the
+# output has been vetted. You can instead pass the names of individual
+# directories, including those that haven't been approved. So:
+#
+# update-copyright.pl --this-year
+#
+# is the command that would be used at the beginning of a year to update
+# all copyright notices (and possibly at other times to check whether
+# new files have been added with old years). On the other hand:
+#
+# update-copyright.pl --this-year libjava
+#
+# would run the script on just libjava/.
+#
+# This script was copied from gcc's contrib/ and modified to suit
+# binutils. In contrast to the gcc script, this one will update
+# the testsuite and --version output strings too.
