accsupp – Better accessibility support for PDF files

Since PDF 1.5 por­tions of a page can be marked for bet­ter ac­ces­si­bil­ity sup­port. For ex­am­ple, re­place­ment texts or ex­pan­sions of ab­bre­vi­a­tions can be pro­vided. This pack­age starts with pro­vid­ing a min­i­mal low-level in­ter­face for pro­gram­mers; its sta­tus is ex­per­i­men­tal.
The pack­age is part of the oberdiek bun­dle.
