The package is designed to aid the author writing linear programming formulations, one restriction at a time. With the package, one can easily label equations, formulations can span multiple pages and several elements of the layout (such as spacing, texts and equation tags) are also customizable. Besides linear programming formulations, this package can also be used to display any series of aligned equations with easy labeling/referencing and other customization options.
