-[02.23.2003] Dave Glowacki <dglo@hyde.ssec.wisc.edu> has added
-(1) file name and line numbers to the error messages, (2)
-AssertDblEquals for doubles, (3) Assert<X>Equals_Msg version of
-all the Assert<X>Equals to pass in optional message which is
-printed out on assert failure.
+These people have contributed useful code changes to the CuTest project.
