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.
