Groovy CLI Parameters Made Easy
After getting thoroughly frustrated with the CliBuilder ( groovy.util.CliBuilder ), for its lack of documentation and unintuitive usage, I stumbled upon GOP (groovy-option-parser). Its almost exactly what I was looking for.GOP makes processing Groovy command line parameters (args) easy. Checkout the synopsis on its project page.
On a side note, Groovy really needs a CPAN.org equivalent. It has a fanastic runtime dependency loading/resolving system in Grape. It just need a single home/community for people to share modules just like this one.
