This is to announce a new release of the Tk Tree widget for Tk4.0.
This version contains (optional) support for [incr Tcl] version 2.0.

I copied the file to ftp.aud.alcatel.com:/tcl/incoming and it should
eventually show up in:

	ftp.aud.alcatel.com:/tcl/extensions/tree-4.0.3.tar.gz

With the tree widget, you can display a tree in a Tk canvas. The nodes
can be made up of any number of canvas items or even other Tk widgets.
You create the objects that make up a node and the line that connects
it to its parent and pass them to the tree widget. After this the tree
widget manages the positions of the nodes and end points of the tree
lines.  Operations are available for inserting, moving and removing
nodes and subtrees and for querrying the position of a node in the
tree. The tree can be displayed horizontally or vertically.

** Changes since the previous version:

- ported to Itcl2.0 (but itcl is optional)

- modified configure script and Makefile to use Itcl, BLT and TclX
  only if found. (Edit Makefile to change this)

- removed dependency on TclX, BLT and Itcl.

- removed all itcl classes, except the "Tree" class, which was
  contributed by Mark Ulferts. (When I am done porting the other
  itcl classes, I may contribute them separately)
