+//
+// Contents
+//
+
+The Closure Compiler performs checking, instrumentation, and
+optimizations on JavaScript code. The purpose of this README is to
+explain how to build and run the Closure Compiler.
+
+The Closure Compiler requires Java 6 or higher.
+http://www.java.com/
+
+
+//
+// Building The Closure Compiler
+//
+
+There are three ways to get a Closure Compiler executable.
+
+1) Use one we built for you.
+
+Pre-built Closure binaries can be found at
+http://code.google.com/p/closure-compiler/downloads/list
+
+
+2) Check out the source and build it with Apache Ant.
+
+First, check out the full source tree of the Closure Compiler. There
+are instructions on how to do this at the project site.
+http://code.google.com/p/closure-compiler/source/checkout
+
+Apache Ant is a cross-platform build tool.
+http://ant.apache.org/
+
+At the root of the source tree, there is an Ant file named
+build.xml. To use it, navigate to the same directory and type the
+command
+
+ant jar
+
+This will produce a jar file called "build/compiler.jar".
+
+
+3) Check out the source and build it with Eclipse.
+
+Eclipse is a cross-platform IDE.
+http://www.eclipse.org/
+
+Under Eclipse's File menu, click "New > Project ..." and create a
+"Java Project." You will see an options screen. Give the project a
+name, select "Create project from existing source," and choose the
+root of the checked-out source tree as the existing directory. Verify
+that you are using JRE version 6 or higher.
+
+Eclipse can use the build.xml file to discover rules. When you
+navigate to the build.xml file, you will see all the build rules in
+the "Outline" pane. Run the "jar" rule to build the compiler in
+build/compiler.jar.
+
+
+//
+// Running The Closure Compiler
+//
+
+Once you have the jar binary, running the Closure Compiler is straightforward.
+
+On the command line, type
+
+java -jar compiler.jar
+
+This starts the compiler in interactive mode. Type
+
+var x = 17 + 25;
+
+then hit "Enter", then hit "Ctrl-Z" (on Windows) or "Ctrl-D" (on Mac or Linux)
+and "Enter" again. The Compiler will respond:
+
+var x=42;
+
+The Closure Compiler has many options for reading input from a file,
+writing output to a file, checking your code, and running
+optimizations. To learn more, type
+
+java -jar compiler.jar --help
+
+You can read more detailed documentation about the many flags at
+http://code.google.com/closure/compiler/docs/gettingstarted_app.html
+
+
+//
+// Compiling Multiple Scripts
+//
+
+If you have multiple scripts, you should compile them all together with
+one compile command.
+
+java -jar compiler.jar --js=in1.js --js=in2.js ... --js_output_file=out.js
+
+The Closure Compiler will concatenate the files in the order they're
+passed at the command line.
+
+If you need to compile many, many scripts together, you may start to
+run into problems with managing dependencies between scripts. You
+should check out the Closure Library. It contains functions for
+enforcing dependencies between scripts, and a tool called calcdeps.py
+that knows how to give scripts to the Closure Compiler in the right
+order.
