alltt – Every­thing in tt font, but obey com­mands and line end­ings

The alltt pack­age de­fines the alltt en­vi­ron­ment which is like the ver­ba­tim en­vi­ron­ment ex­cept that \ and braces have their usual mean­ings. Thus, other com­mands and en­vi­ron­ments can ap­pear within an alltt en­vi­ron­ment.
The pack­age is part of the LaTeX dis­tri­bu­tion.
