A LaTeX macro file modifying the JAMTimes package (expanded (widened) Times-Roman-like fonts used by the Jour­nal d'Anal­yse Mathé­ma­tique) in various ways, among them making the width of plus and minus signs equal to each other.  Boris Veytsman, author of the JAMTimes package, saw some merit in this macro file.  (Original version 2015, current version March 2020, reflecting version 1.625 (2020/03/02) of Michael Sharpe's newtxmath.sty from the newtx package at the CTAN archive.)
