This updated showHelp method for the commandline.scala file may work (note: no guarantee that other changes not needed to be made elsewhere in your source)
def showHelp(out : PrintStream) : Unit = {
var width = 0
for(i <- opts) {
val w = i.longName.length
if(w > width) width = w
}
width += 2
out.print(helpHeader)
for(i <- opts) {
if (i.shortName != None) out.print(" -" + i.shortName.get) else out.print(" ")
out.print(" --")
out.print(i.longName)
for(j <- Iterator.range(0, width - i.longName.length))
out.print(' ')
out.println(i.description)
}
}

a) There's a bug in CommandLineParser that causes it to print short options
in help text as Some(c) instead of just c.
