JOpt Simple incorporated into OpenJDK
"I thought you might be interested to know that we're using your jopt-simple library in the open-source Java Development Kit. Thanks for writing such a nice little library! It's far cleaner than any of the other alternatives out there."
Great feedback! If you need to parse command line options with a minimum of fuss, please check out JOpt Simple 3.0. I look forward to even more widespread adoption of the library.
