------------------------------------
Simple fix, as suggested by Jake:
{code:title=VectorDumper.java|borderStyle=solid}
//added .withOption(helpOpt)
Group group =
gbuilder.withName("Options").withOption(seqOpt).withOption(outputOpt)
.withOption(dictTypeOpt).withOption(dictOpt).withOption(csvOpt)
.withOption(vectorAsKeyOpt).withOption(printKeyOpt).withOption(sizeOpt)
.withOption(helpOpt).create();
{code}
