I have made some tests to compare serialization of different types of data different archives and to compare against raw i/o. So far so good. Now I would like to alter my test/Jamfile to achieve the following: a) I would like to run a command after the test run to display the size of the test executable. b) I would like to run a command (gprof) after the test for certain tests. I would hope that the output of these post processing command would appear in the output log of the standard output. c) I would like to inhibit the running of these tests when the build is in debug mode. d) I intend to uses these in my own environment as this would impose extra burden on testing and I don't really need to run this stuff except for once in a while. However, I'm am curious how one achieves the effect of the config_info test on the main test matrix whereby the test passes but still produces a link to the test output. Robert Ramey
