The package 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.
Binary packages can be installed with the high-level tool pkgin (which can be installed with pkg_add) or pkg_add(1) (installed by default). The NetBSD packages collection is also designed to permit easy installation from source.
The pkg_admin audit command locates any installed package which has been mentioned in security advisories as having vulnerabilities.
Please note the vulnerabilities database might not be fully accurate, and not every bug is exploitable with every configuration.
