I have some unit tests that all use <font size="2">BOOST_AUTO_TEST_CASE.  Is there a way for me to hook into the main function before any of my test cases are run to perform initialization, involving the command line arguments that were passed to the executable?  Currently there is no main function, it&#39;s defined inside the boost headers, and I don&#39;t see an obvious way of hooking into it.</font>
