Quoting Håvard Korsvoll (korsvoll@skulelinux.no):
So long I have been using a script in d-i svn called gettext-helper. Petter has made this script. I have customized it for myself, but my scripting knowledge is poor, so I haven't committed my changes. I suppose your script will do the same as this script, so I plan on using your script in the future. But I haven't had time to look at it yet. Håvard
Hmmm, looks like we invented the wheel twice..:-)
Petter, I move your script into script/l10n-utilities
