at – Short commands starting '@'

The at pack­age re­moves a lot of te­dious typ­ing that ends up in LaTeX doc­u­ments by ex­pand­ing the num­ber of short com­mand names avail­able. The new com­mand names be­gin with the ‘@’ char­ac­ter, rather than the con­ven­tional ‘\’, so you can tell them apart.
The pack­age is part of the mdw­tools bun­dle.
