list­ing – Pro­duce for­mat­ted pro­gram list­ings

The list­ing en­vi­ron­ment is pro­vided and is sim­i­lar to fig­ure and ta­ble, al­though it is not a float­ing en­vi­ron­ment. In­cludes sup­port for \cap­tion, \la­bel, \ref, and in­tro­duces \listoflist­ings, \list­ing­name, \listlist­ing­name. It pro­duces a .lol file. It does not change \@make­cap­tion (un­less the op­tion big­cap­tions is used), so pack­ages that change the lay­out of \cap­tion still work.
