+--  This package contains the routines for Ada.Text_IO.Decimal_IO that are
+--  shared among separate instantiations of this package. The routines in
+--  the package are identical semantically to those declared in Text_IO,
+--  except that default values have been supplied by the generic, and the
+--  Num parameter has been replaced by Integer or Long_Long_Integer, with
+--  an additional Scale parameter giving the value of Num'Scale. In addition
+--  the Get routines return the value rather than store it in an Out parameter.
