JqPlot - which tool can be used to minimize jqPlot JavaScript files

I made some changes to one of the jqPlot ( jqplot.highlighter.js) plugin files , and I would like to minimize it before deployment.

Does anyone know that they use jqPlot tools to minimize jqPlot related .js files? Perhaps they are using JSMin?

In the jqplot.json2.jsfile, I found:

This code should be minified before deployment.
See http://javascript.crockford.com/jsmin.html

But I wanted to double check the sequence.

Many thanks
