Yes, I could probably do that, but I expected those tools to work on
any system, without having to install additional packages. If I have
to install some extra stuff on my system (and none of the systems I
have come with libisl19, so I'd have to mess around quite a bit), it
makes those tools you provide a lot less convenient to use.

It would be great if you could rebuild them with libisl integrated, so
that it doesn't depend on the system anymore.

Thanks,
