The file as presented may be run to produce an example of the output that may be expected: text may be enclosed in rectangular or in rounded-corner (what LaTeX calls ‘oval’) boxes, and the background of the box is shaded.

The technique of using PostScript specials (thus tying use to dvips-based production) contrasts with the specially-concocted fonts used by the shade package.
