Hi Xiaowen:

Since I'm not "down in the trenches" (and least not in all ones), the
following suggestions should be taken with a grain of salt.

First, this looks like a clean proposal to me. But as I said, I'm not
down in the trenches, so we need to hear back from the main Kepler
developers. Don't know whether an actual vote is necessary (my
understanding is that it's done only rarely), but maybe it would help.

As for the timetable of the suggested changes: I think given that
there may be many people who are affected, we could do these changes
incrementally, one directory at a time or so. Maybe after discussing
with the other KEpler developers Ilkay and you could do this

Note that there is a kepler irc channel were folks meet and chat about 
these things with quick turnaround times (the irc info should be on
the Kepler site -- and if not, should go there).

just my $0.02

XX> A user can run the kepler profile by doing:
XX> java -classpath "..." ptolemy.vergil.VergilApplication -kepler
XX> while a user who's more interested in running only geon can do:
XX> java -classpath "..." ptolemy.vergil.VergilApplication -geon

XX> The major benefits of this is that we wouldn't have to muck around in
XX> Ptolemy II's installation any more.  Also we can organize our
XX> configuration files more cleanly.
XX> The only downside is that it would be a change that would affect all
XX> Kepler developers.
XX> I'm not sure whether I should propse a vote on this.  Ideally, I'd like
XX> to go ahead and implement this by the end of this week, if there are no

XX> Thanks,
