[jQuery](http://jquery.com/) - New Wave Javascript
================================

What you need to build your own jQuery
---------------------------------------
* Make sure that you have Java installed (if you want to build a minified version of jQuery).
If not, go to this page and download "Java Runtime Environment (JRE) 5.0"  
[http://java.sun.com/javase/downloads/index.jsp](http://java.sun.com/javase/downloads/index.jsp)

Build Options
--------------

You now have **three** options for building jQuery:

* **`make`**: If you have access to common UNIX commands (like `make`, `mkdir`, `rm`, `cat`, and `echo`) then simply type `make` to build all the components.

* **`rake`**: If you have Ruby Rake installed, you can simply type `rake` to build all the components. This method works on both Windows and UNIX/Linux systems.

* **`ant`**: If you have Ant installed (or are on Windows and don't have access to make). You can download Ant from here: [http://ant.apache.org/bindownload.cgi](http://ant.apache.org/bindownload.cgi).

How to build your own jQuery
-----------------------------

*Note: If you are using either `rake` or `ant`, substitute your chosen method in place of `make` in the examples below. They work identically for all intents and purposes. Quick reference is also available for `rake` by typing `rake -T` in the `jquery` directory.*

In the main directory of the distribution (the one that this file is in), type
the following to make all versions of jQuery:

    make

*Here are each of the individual items that are buildable from the Makefile:*

    make init

Pull in all the external dependencies (QUnit, Sizzle) for the project.

    make jquery

The standard, uncompressed, jQuery code.  
Makes: `./dist/jquery.js`

    make min

A compressed version of jQuery (made the Closure Compiler).  
Makes: `./dist/jquery.min.js`

    make lint

Tests a build of jQuery against JSLint, looking for potential errors or bits of confusing code.

    make selector

Builds the selector library for jQuery from Sizzle.  
Makes: `./src/selector.js`

Finally, you can remove all the built files using the command:
  
    make clean

Building to a different directory
----------------------------------

If you want to install jQuery to a location that is not this directory, you can...

**Make only:** Specify the PREFIX directory, for example:
  
    make PREFIX=/home/john/test/ [command]
    
With this example, the output files would be contained in `/home/john/test/dist/`

**Rake only:** Define the DIST_DIR directory, for example:

    rake DIST_DIR=/home/john/test/ [command]
    
With this example, the output files would be contained in `/home/john/test/`

*In both examples, `[command]` is optional.*

**Ant only:** You cannot currently build to another directory when using Ant.
