Does ‘build’ mean beta or (stable) preview here?  Then we should 
append ‘0.0.0-’ or similar, like we do for git snapshots, to the 
front in case upstream releases a 1.x at some point.

Otherwise, ‘20’'s fine, really.

Thank you both!  I'm building it now.

Minor typo (‘embeeded’).  Are you the ‘I’ in the patch?  Is it 
pending upstream application?  If so, a link to the upstream bug 
report/commit would be nice.

Why not the default RelWithDebInfo?  Please note in a comment.

Mkay I guess.  No point in a codebase chock-full of repetitive 
alists if we're not going to take advantage of it once in a while 
:-)

I'd put both at the end with a single

  ;; Fonts for the ‘unbundle-fonts’ phase.  Case matters in name!

comment.

I think Debian(-derived) descriptions are OK but I prefer 
yours/upstream's anyway.

At least Culmus and Sinhala are GPL2-only.  The title screen also 
says ‘GNU General Public License V2.0’.

Which parts are gpl3+?  That sounds problematic.

It's built now, I will test it extensively on the bus…

Thanks!
