yup.

we've got a consensus of two now -- good enough for me ;-)

A clear advantage of universal binaries is that you can have one set of binaries and don't have to pick which architecture gets the most obvious installation directory (e.g. /lib vs. /lib64 on a lot of Linux systems).

yeah -- I do like them, when they work...

it would be best for any change to get merged around the same time as
the packaging stuff -- so there is only one versin out there. But I
agree, the short names are nice -- if the only place anyone would get
the names is distutils, then we're fine.

This is all closer that I thought was -- nice!
