-    "GNU Units converts quantities expressed in various systems of
-measurement to their equivalents in other systems of measurement.  Like
-many similar programs, it can handle multiplicative scale changes.  It can
-also handle nonlinear conversions such as Fahrenheit to Celsius or wire
-gauge, and it can convert from and to sums of units, such as converting
-between meters and feet plus inches.
-
-Beyond simple unit conversions, GNU Units can be used as a general-purpose
-scientific calculator that keeps track of units in its calculations.  You
-can form arbitrary complex mathematical expressions of dimensions including
-sums, products, quotients, powers, and even roots of dimensions.  Thus you
-can ensure accuracy and dimensional consistency when working with long
-expressions that involve many different units that may combine in complex
-ways.
-
-The units are defined in an external data file.  You can use the extensive
-data file that comes with this program, or you can provide your own data
-file to suit your needs.  You can also use your own data file to supplement
-the standard data file.")
