CTAN has a new package: xyling

[CTAN Announcements]

On Mon, 31 Jul 2006, Ralf Vogel submitted a new package called 

  xyling

to CTAN.

Location on CTAN: macros/latex/contrib/xyling

Summary description:  Macros to draw syntactic trees and similar graphical 
  objects used in linguistics literature, based on xypic.

License type: lppl

Announcement text: 
----------------------------------------------------------------------

The macros in this package model the construction of linguistic tree 
structures as a genuinely graphical problem: they contain two types of 
objects, BRANCHES and NODE LABELS, and these are positioned relative to a 
GRID. It is essential that each of these three elements is constructed 
independent of the other two, and hence they can be modified without 
unwanted side effects.The macros are based on the xypic package.

Thanks for the upload.
