re­size­gather – Au­to­mat­i­cally re­size overly large equa­tions

Equa­tions that are too large are re­sized to fit the avail­able space. The en­vi­ron­ment ‘gather’ of pack­age ams­math is sup­ported. Also the en­vi­ron­ments ‘equa­tion’ and ‘dis­play­math’ are re­de­fined us­ing ‘gather’ and its starred ver­sion.
The pack­age is part of the oberdiek bun­dle.
