Illustrator Align Text Script

// script.name = alignText.jsx;
// script.description = aligns selected text;
// script.requirements = an open document and one or more text frames selected;
// script.parent = CarlosCanto // 01/27/2013;
// script.elegant = false;


// Usage: select one or more text frames and click on any of the alignment or justification list options to align or justify
//               it works with CS4 and above (not tested on earlier versions, so it may work as far as CS2)
//
// Known Issues: Align Left is broken, as a workaround, try using 'Justify Last Line Left' on point text,
//                              on Area text it may not be what you need.
