---------------
-This HAT source originally came from the http://hat.dev.java.net site.
-
-The utility has been named 'jhat' in the JDK, it is basically the same tool.
-
-Q: Where do I make changes? In the JDK or hat.dev.java.net?
-
-A: It depends on whether the change is intended for the JDK jhat version only,
-   or expected to be given back to the java.net project.
-   In general, we should putback changes to the java.net project and
-   bringover those changes to the JDK.
-
-Q: I want to build just jhat.jar instead of building entire JDK. What should I do?
-
-A: Use ant makefile (build.xml) in the current directory. This builds just the
-jhat sources and creates jhat.jar under ./build directory.
-
-To run the built jhat.jar, you can use the command:
-
-    java -jar build/jhat.jar heap_dump
