Mathtools provides a series of packages designed to enhance the appearance of documents containing a lot of mathematics. The main backbone is amsmath, so those unfamiliar with this required part of the LaTeX system will probably not find the packages very useful. Mathtools provides many useful tools for mathematical typesetting. It is based on amsmath and fixes various deficiencies of amsmath and standard LaTeX. It provides: Extensible symbols, such as brackets, arrows, harpoons, etc.; Various symbols such as \coloneqq (:=); Easy creation of new tag forms; Showing equation numbers only for referenced equations; Extensible arrows, harpoons and hookarrows; Starred versions of the amsmath matrix environments for specifying the column alignment; More building blocks: multlined, cases-like environments, new gathered environments; Maths versions of \makebox, \llap, \rlap etc.; Cramped math styles; and more... Mathtools requires mhsetup.
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.
