Hello, in the Git repo of xz, we have the Autotools stack for man page translations for more than a year. The German versions are already shipped with v5.2.5. But what ist the blocker which still prevents you from creating an intermediate tarball, send it to the TP coordinator and tell him to create a new domain named "xz-man"? If nobody knows that the man pages are translatable, we will never get other than the German ones.
Best Regards, Mario
