+Math::Calc::Units is a simple calculator that keeps track of units.  It
+currently handles combinations of byte sizes and duration only, although
+adding any other multiplicative types is easy.  Any unknown type is
+treated as a unique user type (with some effort to map English plurals
+to their singular forms).
