The feynmf package provides an interface to Metafont (inspired by the facilities of mfpic) to use simple structure specifications to produce relatively complex diagrams. (The feynmp package, also part of this bundle, uses MetaPost in the same way.) While the package was designed for Feynman diagrams, it could in principle be used for diagrams in graph and similar theories, where the structure is semi-algorithmically determined.
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.
