Download the YUI (Yahoo User Interface) Compressor which compresses javascript and css files hence making the file size smaller and execution speed faster.

It is very simple to use this application to compress the files. All you need to have is a java installation in your machine.
$ java -jar yuicompressor-4.1.2.jar cufon.js -o cufon-min.js
The above is the command that you need to execute from command line to generate the minimized version of the javascript file.
(In the example above, I have used the cufon script which is an alternative to sIFR way of handling different fonts across wide range of browsers)
