+      The UDUNITS package supports units of physical quantities. Its C library
+      provides for arithmetic manipulation of units and for conversion of
+      numeric values between compatible units. The package contains an extensive
+      unit database, which is in XML format and user-extendable. The package
+      also contains a command-line utility for investigating units and
+      converting values.
