   3 # Fix GPLv2 license blurbs that have the old FSF address at Temple Street,
   4 # instead of the Franklin Street one. Files to be fixed are read from
   5 # stdin. Typical usage would be:
   6 #
   7 #   ./xt/find-license-problems . |
   8 #   grep -vFx -f ./xt/fix-old-fsf-address.exclude |
   9 #   ./xt/fix-old-fsf-address
