Re: source package format 3.0 with multiple tar balls
dpkg-source unpacks the second tarball to a subdirectory based on the
The upstream tarball contains a manual subdirectory:
$ tar tf luatex-beta-0.64.0-doc.tar.bz2 | head -n2
So the manual/manual thing comes from the orig.tar suffix plus the
subdir inside the upstream tarball.
So, two options:
File a bug on dpkg-source asking for it to strip the additional levels
of subdirectories with single entries until a file or a directory with
multiple files/directories in it shows up.
Adapt your packaging to use the additional level of subdirectory. This
would be the simpler option, unless I am missing something.
BTW, upstream uses a -doc tarball suffix, why not use that?
