Is there a source code formatter for Groovy? [closed]

I use the commercial version of Jalopy for my Java projects but it doesn't work on Groovy files. IntelliJ has a serviceable formatter but I don't like requiring a particular IDE.

What is source code formatter?

Source Code Format means the source (or human readable) format of the Software when it has not been compiled and is not in a machine readable state. Examples include, but are not limited to Objective C, C++, Java, C#, JSP, XML, ASP and PHP. Sample 1.

I've found that BUSL works really well on Groovy files. It's standalone too, so you can use it from your text editor or whatever.
