Thanks for this list.

The list includes the contributors of BRLTTY and Hyphen as well. I've
listed them all because it is impossible to trace back who actually
wrote the stuff that ended up in liblouis. As both libraries are LGPL
2.1, it's not necessary to ask for their permission when relicensing
liblouis under that same license AFAIK.

While Hyphen is indeed LGPL2.1, BRLTTY is not. I just checked the license and it appears to be GPL (see http://mielke.cc/brltty/download.html). I don't know which parts of liblouis are from BRLTTY and I don't know why we are allowed to redistribute BRLTTY code under LGPLv3. Presumably the BRLTTY people gave John the permission?

Thanks
Christian
