+
+# This script adjusts the copyright notices at the top of source files
+# so that they have the form:
+#
+#   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.
+#
+# The script also doesn't change testsuite files, except those in
+# libstdc++-v3.  This is because libstdc++-v3 has a conformance testsuite,
+# while most tests in other directories are just things that failed at some
+# point in the past.
+#
+# 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/.
+#
+# Note that things like --version output strings must be updated before
+# this script is run.  There's already a separate procedure for that.
