  10 # This script adjusts the copyright notices at the top of source files
  11 # so that they have the form:
  12 #
  13 #   Copyright XXXX-YYYY Free Software Foundation, Inc.
  14 #
  15 # It doesn't change code that is known to be maintained elsewhere or
  16 # that carries a non-FSF copyright.
  17 #
  18 # The script also doesn't change testsuite files, except those in
  19 # libstdc++-v3.  This is because libstdc++-v3 has a conformance testsuite,
  20 # while most tests in other directories are just things that failed at some
  21 # point in the past.
  22 #
  23 # Pass --this-year to the script if you want it to add the current year
  24 # to all applicable notices.  Pass --quilt if you are using quilt and
  25 # want files to be added to the quilt before being changed.
  26 #
  27 # By default the script will update all directories for which the
  28 # output has been vetted.  You can instead pass the names of individual
  29 # directories, including those that haven't been approved.  So:
  30 #
  31 #    update-copyright.py --this-year
  32 #
  33 # is the command that would be used at the beginning of a year to update
  34 # all copyright notices (and possibly at other times to check whether
  35 # new files have been added with old years).  On the other hand:
  36 #
  37 #    update-copyright.py --this-year libitm
  38 #
  39 # would run the script on just libitm/.
  40 #
  41 # Note that things like --version output strings must be updated before
  42 # this script is run.  There's already a separate procedure for that.
