\shapepar is a macro to typeset paragraphs in a specific shape. The size is adjusted automatically so that the entire shape is filled with text. There may not be displayed maths or \vadjust material (no \vspace) in the argument of \shapepar. The macros work for both LaTeX and plain TeX.

\shapepar works in terms of user-defined shapes, though the package does provide some predefined shapes. The tedium of creating these polygon definitions may be alleviated by using the shapepatch extension to transfig which will convert xfig output to \shapepar polygon form.
