Sorry, it took me longer than I meant to to get back to this. Looks
basically, good, but there's two little problems. First, they're named .bz2,
but the files seem to actually be gzipped. And second, they're named like
festvox_nitech_us_awb_arctic_hts.tar-2.0.bz2
with the version between the ".tar" and the ".bz2". That may confuse some
archiving programs -- I think better would be
festvox_nitech_us_awb_arctic_hts-2.0.tar.bz2
The AWB tarball is missing the file
./festival/lib/voices/us/nitech_us_awb_arctic_hts/COPYING
which should contain the CMU license.
Oh, and it also contains a couple of .orig and .rej files from a failed
patch. (But looks like the change was then made, so it's just junk that
shouldn't be packaged.)
