newtx – Al­ter­na­tive uses of the TX fonts, with im­proved met­rics

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.
