Thank you, and sorry that review takes some time.  I guess that’s the
price to pay when submitting non-trivial packages.  ;-)

OK.  Courier is a standard PostScript font (with a free implementation
by the URW++ foundry), so it’s probably fine.  I don’t know about the
others; it’s probably safe, but perhaps you could ask for advice on the
GNU/Linux-libre mailing list?  (See
<https://lists.nongnu.org/mailman/listinfo/gnu-linux-libre>.)

What you’re writing about libmp/libsec linked into ‘emu’ sounds like it
could be a GPL violation.  Again, to be sure, I’d suggest getting
feedback from the GNU/Linux-libre mailing list (in a separate thread.)

Sounds good.

Thank you!
