Re: [equinox-dev] app model demo

[Thomas Watson <tjwatson@xxxxxxxxxx>]

I updated the wiki (see http://wiki.eclipse.org/index.php/Equinox_Demos#Application_Model).
 I spent some time creating a UI front end.  Its nothing fancy
but it seems to work good enough.  I did not spend any time making
the console commands any better.  I don't want to spend any more time
on this demo right now.

TODOs after EclipseCon

- make app console commands more user
friendly
- provide instructions for running on
foundation.

Tom.

Can you put up instructions of rhow to run this on Foundation?

Console is definitely good enough. Actually I'm thinking it is even better.
 feels retro but new at the same time :-)

Ok on the registry.  Some configuration that does not include the
runtime (and its prereqs would be cool)  I could not get that to wokr.
