+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.
