The Inbox: GraphicsExternal-cbc.2.mcz

The class comment of ExternalScreen explains the intent:

  "I represent a DisplayScreen that is not part of the Squeak universe.
  Subclasses must implement the appropriate primitives for creating,
  destroying and allocating the appropriate external objects."

Currently these classes, and any associated methods elsewhere in the image,
are in category "Etoys-Squeakland-Graphics-External".

So a first guess would be that they should be in "Graphics-External", but
that does not work because it is a subset of the existing "Graphics". So
instead it might be "External-Graphics". But there will probably be other
things that we will see as "external" to the "Squeak universe", so I
would propose this:

The package name on source.squeak.org should be "External". The class
categories for these external graphics classes and methods should
be "External-Graphics".

+1.  But what about the project name?  i.e. we have trunk, inbox etc.  Where would External-Foo go in that constellation?
