Hi Eric,

thanks for the swift reply.

Great!

Ah, but people coming to get the package may view it as separate,
particularly when their linux distribution emphasises the differences
between amd64 and i386 by providing complete sets of binaries for each.
That's what prompted the question; it was unclear from just the
information on the web pages if amd64 was supported.
Ditto for, say, linux on sparc.

We still need to build ATLOD, that's the only outstanding task I am
aware of. Also some local users have written their own versions of
tasks that they need to build. So we will probably continue building
our own binaries.

Thanks again
