+-- OBJECTIVE:
+--      Check that the function Log provides correct results.
+--
+-- TEST DESCRIPTION:
+--      This test examines both the version of Log resulting from the 
+--      instantiation of the Ada.Numerics.Generic_Elementary_Functions with 
+--      with a type derived from type Float,as well as the preinstantiated
+--      version of this package for type Float.
+--      Prescribed results, including instances prescribed to raise 
+--      exceptions, are examined in the test cases.  In addition, 
+--      certain evaluations are performed where the actual function result 
+--      is compared with the expected result (within an epsilon range of 
+--      accuracy).
+--
+-- TEST FILES:
+--      The following files comprise this test:
