+Using NetBeans to work on the langtools repository.
+
+Netbeans 6.0 or later is recommended.
+
+The "langtools" project in this directory allows you to
+edit, run, test and debug the tools in the OpenJDK langtools
+repository.
+
+The repository contains a number of tools:
+    javac, javadoc and its doclets, javah and javap.
+
+Build Properties.
+
+To build this repository, you must set some properties for Ant.
+You can set these properties in a number of ways:
+
+- Set the properties in the Properties panel under Tool> Options> Ant.
+  Properties set this way will apply globally to all the langtools 
+  repositories you may be working on.
+
+- Create a file build.properties in the root directory of a
+  langtools repository, and set the properties in that file.
+  These properties will be specific to that repository.
+
+To build the repository, at a minimum you must set the "boot.java.home"
+property.  To run the tools, you must also set "target.java.home". To
+run the regression tests, you must set "jtreg.home".
+
+By default, the build and test targets will build and test all
+of these tools. The run and debug targets will prompt you for the
+name of a tool to execute.
+
+As an alternative, you can focus on a single tool.  When you do
+this, you will still see all the source code for all the tools,
+but the various Ant targets will now be focussed on the selected tool.
+To focus on a tool, bring up the context menu on the "langtools"
+project (i.e. right-click on the project) and select "Select Tool".
+This brings up a dialog which allows you to specify which tool you
+wish to work on, and the arguments to use if and when you run it.
