GETOPT
======
Utility to parse command line arguments using same/similar conventions as the Unix getopt() function.


USAGE
-----

# Create a instance of the parser
var go = new Getopt();

# Add command line options to parse
# For example, to store a string value into the field 'f'
go.addSwitch( ["f"], store( "filename", TString ) );

# Parse an array of arguments (like returned by neko.Sys.args())
go.parse( ["-f","myfile"] );
# Or
go.parseString( "-f myfile" );

# Your value is now available at
trace( go.opt.filename ); // myfile
