Version 2.2.4 (20061030) ======================== A checker for YES/NO answers is added. If the program being tested outputs neither YES no NO answers (case-insensitive), or letter case does not match the correct answer, "Presentation error" is reported. "Wrong answer" is reported otherwise. A few memory leaks are fixed. A bug of incorrect removal session ids which caused `userlist-server' abort is fixed. Necessary command line options are passed to the `sendmail' program, so sending registration and statistics email now works.
