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