JOpt Simple 3.1-beta1 released

JOpt Simple is my Java library for parsing command-line options. Version 3.1 adds the ability to convert arguments of options to Java types via converter objects. These are useful for types that do not meet the requirements of ArgumentAcceptingOptionSpec#ofType(), or for which you might want to do things like regex matching before passing the values along unchanged. Check out the new classes in package joptsimple.util for some examples. Have a look-see and let me know what you think.

JOpt Simple 3.0.1 released

JOpt Simple is my Java library for parsing command-line options. Release 3.0.1 has no new features, but fixes a dependency problem for Maven users, so that by declaring a Maven dependency on jopt-simple, you don't end up pulling down Ant and the transitive closure of its dependencies.

JOpt Simple incorporated into OpenJDK

Via email from Mark Reinhold, Principal Engineer at Sun Microsystems -- it appears that JOpt Simple is being used for some of the command line tools in the 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.
