As recommended in http://www.gnu.org/licenses/gpl-howto.en.html. This is the result of: $ git grep -El Mass\|Temple\|Franklin | xargs ./fsf.pl Where fsf.pl is: #!/usr/bin/perl -w -pi.bak -0777 my $repl = 'If not, see <http://www.gnu.org/licenses/>.'; my $br = qr/(?:\s*\n\s*(?:[\*\#]|\/\/|\.\\" )?\s*|\s+)/; my $inwt = qr/[Ii]f${br}not,${br}write${br}(?:to${br})?the${br}Free${br}Software${br}Foundation,(?:${br}Inc\.,)?/; my $mass = qr/675${br}Mass${br}Ave,?${br}Cambridge,?${br}MA${br}02139,?${br}USA,?\.?/; my $franklin = qr/51${br}Franklin${br}St(?:reet)?(?:,${br}| - )Fifth${br}Floor,?${br}Boston,?${br}MA,?${br}02110-1301,?${br}USA,?\.?/; my $temple = qr/59${br}Temple${br}Place(?:,${br}| - )Suite${br}330,?${br}Boston,?${br}MA,?${br}021110?-1307,?${br}USA,?\.?/; s|$inwt$br$mass|$repl|m; s|$inwt$br$franklin|$repl|m; s|$inwt$br$temple|$repl|m; The only remaining mentions of these addresses are in COPYING files which I haven't touched. Some of the changed files are imports from elsewhere, however filtering them out is tricky, I think it is tolerable to have these files be modified here and then perhaps reverted on the next sync, since it's only 1-2 lines and obvious what is going on.
