The bundle splits txfonts.sty (from the TX fonts distribution) into two independent packages, ntxtext.sty and ntxmath.sty, each with fixes and enhancements.
Ntxmath’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.
Ntxmath can also use the maths italic font provided with the garamondx package, thus offering a garamond-alike text-with-maths combination.
