The guidelines for this library are:
 
   - All features are intended to end up in a stable platform library
     when they're ready.

   - All features must be "sponsored" by the maintainer of the
     platform library the feature is targetting. Features 
     without sponsors do not go in.

   - In sponsoring a feature, maintainers are saying that think a
     feature along these lines makes sense in their platform library,
     and that the initial implementation looks at least approximately
     like what they want.

   - As soon as a feature has been shipped in stable form in a
     platform library, it comes out of libegg.

   - If a maintainer decides that a feature doesn't make sense after
     all, or that a radically different approach is required, they can
     "unsponsor" the feature and the feature will be removed from 
     libegg.

   - All patches must be approved by the sponsor of the feature being
     patched, though the sponsor maintainer may choose to delegate
     patch review duties. (To the person implementing the feature, for
     example.)

   - Maintainers will probably do a final review/revision of features
     before movinng them from prototype library to platform library.

   - Features can only have dependencies that are shared by the target
     platform library. For example you can't use libgnome to implement
     a feature targetted for GLib. (You can however depend on another
     GLib-targetted libegg feature, of course.)
 
   - Features are in the "egg" namespace not in the platform library
     namespace, and are renamed when they're moved.

   - The API/ABI of libegg can change at any time, though it's
     courteous to coordinate with app developers, cruft should not be
     left in the prototype library for compatibility reasons.

   - The purpose of this library is to test feature APIs and
     implementations, so the library is expected to be a
     work-in-progress, but bug reports and suggestions are extremely
     welcome.

   - Discussion of features should happen on the mailing list for the
     target platform library, but may also be cc'd to
     gnome-libs-devel@gnome.org. Coordination of libegg itself happens
     on gnome-libs-devel@gnome.org.

   - libegg will always depend on the latest stable branches of the
     platform libraries, not on the development branches.

As a special exception to the rule that all features are destined for
a real lib, a hackaround for the lack of a feature that is destined
for a real lib is also allowed. So for example, you could put
EelEllipsizingLabel in here until GTK has label ellipsizing, ASSUMING
that you've verified with the GTK maintainers that GTK will have label
ellipsizing, and ASSUMING that the workaround goes away when the real
feature has gone in.
