en­v­i­ron – A new in­ter­face for en­vi­ron­ments in LaTeX

The pack­age pro­vides the \col­lect@body com­mand (as in ams­math), as well as a \long ver­sion \Col­lect@Body, for col­lect­ing the body text of an en­vi­ron­ment.
Th­ese com­mands are used to de­fine a new au­thor in­ter­face to cre­at­ing new en­vi­ron­ments. For ex­am­ple:   \NewEn­v­i­ron{test} wraps the en­tire en­vi­ron­ment body in square brack­ets, do­ing the right thing in ig­nor­ing lead­ing and trail­ing spaces.
