The result of running etc/update-copyright.py --this-year, fixing all the files whose mode is changed by the script, plus a build with --enable-maintainer-mode --enable-cgen-maint=yes, then checking out */po/*.pot which we don't update frequently. The copy of cgen was with commit d1dd5fcc38ead reverted as that commit breaks building of bfp opcodes files.

# 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

|
|
#
|
|
# 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.
