Like the current Apertium-viewer:

I think its about half of the pairs.

I see youve compiled the Android src yourself :-) The version distributed
with the Android SDK is 700 kb.

Sorry, I wasnt thinking clearly here. I think its not needed by
lttoolbox-java and shouldnt be installed at end users machines. Its needed
for your script apertium-pack-j and belongs to it (perhaps your script
could just reside in SVN)

No, they dont take too much space and I think they should be included.
But thinking again, what you'd do is really guesswork on which files are
needed and re-inventing the 'make install' function. Which files should be
installed is already defined in Makefile.am for each pair.....
