The bundle splits txfonts.sty (from the TX fonts distribution) into two independent packages, newtxtext.sty and newtxmath.sty, each with fixes and enhancements. newtxmath's metrics have been re-evaluated to provide a less tight appearance, and to provide a libertine option that substitutes Libertine italic and Greek letter for the existing math italic and Greek glyphs, making a mathematics package that matches Libertine text quite well. newtxmath can also use the maths italic font provided with the garamondx package, thus offering a garamond-alike text-with-maths combination.
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.
