+     "This package provides a set of m4 macros for drawing high-quality
+electric circuits containing fundamental elements, amplifiers, transistors,
+and basic logic gates to include in TeX, LaTeX, or similar documents.  Some
+tools and examples for other types of diagrams are also included.  The macros
+can be evaluated to drawing commands in the @code{pic} language, which
+contains elements of a simple programming language, and is well-suited to line
+drawings requiring parametric or conditional components, fine tuning,
+significant geometric calculations or repetition, or that are naturally block
+structured or tree structured.  Alternative output macros can create TeX
+output to be read by PSTricks, TikZ commands for use by the PGF bundle, or
+SVG.")
