Hi Christopher,

That was my bad. I forgot to include the names of the new commands in my
comment closing the issue.

To work from ptolemy head, you type in:

ant use-ptolemy-head

To switch back to using the stable version of ptolemy, you type in:

ant use-stable-ptolemy

That is it.

As far as what is default, I tend to think that ant update should probably use
the stable version of Ptolemy. Whatever is default will be what most developers
actually do in practice.

Keep in mind that the difference between the head and the "stable" version of
Ptolemy should only be a few revisions in most cases. Kepler tries to update
the stable version to be the head every single night. Basically, Kepler is
committed to working at the head of Ptolemy, but with a tiny little firewall.

Of course, it is possible to modify Ptolemy itself from Kepler. But, this is
not the default case. I do not think that asking Ptolemy developers using the
Kepler build (which would include Kepler developers who want to modify Ptolemy)
to type in the extra command: 'ant use-ptolemy-head' is much to ask. What do
you think?
