Impressive!

Note to self: we still need to fix the ant-build-system to install a
file containing plain-text references to all inputs to prevent them from
being garbage collected.

Could you add a comment here to explain why this is needed?

I prefer using the make-flags here to set the base.path property.  Have
you tried that?

“Open source”, eh? :)  Please just write “[…] is an implementation of
the […]”.  The second sentence is a bit odd.  I don’t think that’s
information that belongs in a package description.

Thanks!
