This is an implementation of a new tag for the OpenCms taglib that can automatically condense JavaScript and CSS code. The tag is used by enclosing a block of CSS of JavaScript with it, for example:

<cms:minify type="js">
function myFunc() {
  myVar = 123;
  alert( myVar );
}
</cms:jsminify>

The result in this case would be: "function myFunc(){a=123;alert(a)}"

The minification is done through the excellent Yahoo YUI compressor (http://developer.yahoo.com/yui/compressor/) which is also used by the jQuery project and which is, for example, able to condense variable names.
