[OGo-Developer] Adding information to EOModel?

[Adam Tauno Williams]

Is it possible for a bundle to add informatOGoModel.mion (like an
additional table) to OGo's EOModel?  Or 'basic' objects?

I see that Misc/Invoice adds commands ("invoice::set") but
OGoModel/Classes already contains LSInvoice and
Database/OGoModel/OpenGroupware.org_PostgreSQL.eomodel already contains
the invoice tables.

It looks like these files get installed
into /usr/local/lib/opengroupware.org-1.1/commands/OGo.model/Resources/
(at least on my system).  Will it be effective to 'patch' these files
when a bundle is installed (adding additional information to
OpenGroupware.org_PostgreSQL.eomodel)?
