This file describes macro packages contributed to GNU troff. boxes: This stand-alone macro package is a means to provide typographic templates for catalogue generators or similar programs. The general idea is to separate the input data from the layout as much as possible; the only limitation is that vertical box lengths can't exceed the length of a single page -- there is no support for multi-page boxes. mn: Provide margin notes. ul: This add-on macro file defines a macro `.Underline' which underlines its arguments continuously. It is completely transparent to justifying, this is, the text to be underlined (and the text surrounding it) is typeset identically to normal text, without any distortion in filling. Note that you can can use `.Underline' in diversions; it works also across page breaks and is robust against vertical position traps.
