This package puts a grid on the paper. It was written for developers of a class or package who have to put elements on definite locations on a page (e.g. letter class). The grid allows a faster optical check, whether the positions are correct. If the previewer already offers features for measuring, the package might be unnecessary. Otherwise it saves the developer from printing the page and measuring by hand.

The package is part of the bundle.
