+ LingTrees Linguistics Tree-formatting Preprocessor and Macros
+ Avery D Andrews, March 2006
+
+Purpose:
+
+This is a LateX2e package for formatting linguistics trees (upside-down,
+hanging by the root, with slanted branches from mother to daughters),
+consisting of a prepreprocessor written in Python (freely downloadable from
+http://www.python.org or http://www.activestate.com; the latter might be
+easier to get working in Linux), and some LaTeX .sty files. The preprocessor
+allows trees to be entered as indented lists (no brackets to worry about),
+and also deploys line-drawing and various other commands. The macros are
+responsible for the details of positioning. Plain TeX is currently not
+supported.
+
+In addition to the preprocessor itself (trees.py), there's a simple
+GUI for running it by pushing a button in the GUI subdirectory.
+Free-standing executables for Windows may be found at:
+
+ http://arts.anu.edu.au/Linguistics/People/AveryAndrews/Software/latex
+
+The package is probably most suitable for irregularly-branching trees
+with wide and complex node-labels, such as are prevalent for example in
+LFG and HPSG. Other packages that might be worth looking at are pst-jtree
+(good for heavily right-branching trees with small node-labels) and
+qtree (which works with pdflatex). It is an upwards-compatible
+successor to the 'trees' package at CTAN/latex209/contrib/pstrees/trees.
+
+Dependencies:
+
+It requires either the pst-nodes module of the PSTricks, or Emma Pease's
+tree-dvips (with less functionality), both available on CTAN.
+
+License:
+
+ LaTeX macros: LaTeX Project Public License
+ trees.py: GPL 2
+
+Documentation:
+
+The documentation for the macros and preprocessor commands is in the
+file lingtrees.doc.pdf. pst-nodes is accessed thru a partial emulation
+of tree-dvips, documented in pst-tree-dvips-emu.doc.pdf.
+
+For more information, see READMORE.txt and the pdf documentation.
