    (description
-    "GNU C-Graph demonstrates the theory of convolution underlying
-engineering systems and signal analysis.")
+     "GNU C-Graph is a tool for demonstrating the theory of convolution.
+Thus, it can serve as an excellent aid to students of signal and systems
+theory in visualizing the convolution process.  Rather than forcing the
+student to write code, the program offers an intuitive interface with
+interactive dialogs to guide them.")
