The merged version will use the Lucid code for zones.  These are _much_
more efficiently implemented and switching to them is a big win for a number
of Epoch features, including the redisplay model.

Selective display will be fully operational in the merged version.
The redisplay rewrite is in progress right now.  See the note posted
by Jamie Zawinski in alt.lucid-emacs.help for more information on the
merger and expected availability.

The merged version will have scroll bars.

As mentioned above, the zone implementation will be Lucid's extents.
These are already much more efficient than Epoch's zones.  You should
have no problems doing this.

A compatibility package will be available with the merged version, possibly
even before the merged version is released.
