This is to announce a new release of the Tk Tree widget for
Tcl7.5/Tk4.1.  This version contains (optional) support for [incr Tcl]
and [incr Tk] version 2.1.

I copied the file to:

 	ftp://ftp.neosoft.com/tcl/incoming/tree-4.1.tar.gz

 and it should eventually show up in:

	ftp://ftp.neosoft.com/pub/tcl/tree-4.1.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 Itcl2.1/Tk4.1/Tcl7.5 (itcl is optional)

- added configure options: --with-itcl, --with-itk, --with-blt, --with-tclx
  to allow easy configuration with extensions. The default is no extensions
  other than the tree widget, since only one of the demos requires itcl. 
  (BLT and TclX are not used in this version's demos, but may be in a 
  future version...)

- Changed the itk Tree class used. The previous release included a version
  by Mark Ulferts. This version uses an earlier version that I wrote and
  ported to itk2.x. Some of the method names changed because of this.

- replaced the HTML doc with a postscript version and made minor changes
  to the text (for an upcoming O'Reilly book on Tcl extensions).
