The package is provides a PGF/TikZ-based mechanism for drawing
linguistic (and other kinds of) trees. Its main features are: a
packing algorithm which can produce very compact trees; a user-
friendly interface consisting of the familiar bracket encoding
of trees plus the key-value interface to option-setting; many
tree-formatting options, with control over option values of
individual nodes and mechanisms for their manipulation; the
possibility to decorate the tree using the full power of
PGF/TikZ; and an externalization mechanism sensitive to code-
changes.
