Samurai is a GUI flavored tabbed "tail -f" tool. It lets you not only browse any sort of log file but also see visualized CSV files, Java's vebosegc logs and so on. Good for all developers and system administrators.
What's new in Samurai
added support for -verbosegc log generated by IBM JDK1.4.2(tested with JDK1.4.2_08)
