Hmm; I am not sure what to think here. texlive-base is mostly like under
a different license, so it is not unthinking able that there will be a
problem with combing Apache Software with these files. Particularly I do
not like the wording:
Many of the hyphenation files distributed with TeX and its offspring are
licenced under the LaTeX Project Public License (LPPL), which prevents
them from being distributed with Apache software.
That being said I have not actually compared the two licensed to each
other (and I admit I would prefer not having to :P ).
Though the actual reasons given by FOP upstream suggests that part of
this are for political reasons (e.g. the file name restrictions), which
suggests we may be able to ship hyphenation pattern files that do not

Personally I would probably prefer B-Ding on the texlive-source and
generate them during build from the install texlive-source if possible.
Though I have not looked at the texlive-source package, nor how to do
this in FOP.
