+WHOA THERE! It looks like you've got some fancy dashes in your commandline!
+These are *not* the traditional -- dashes that software recognizes. You
+probably got these by copy-pasting from the perldoc for this module as
+rendered by a UTF8-capable formatter. This most typically happens on an OS X
+terminal, but can happen elsewhere too. Please try again after replacing the
+dashes with normal minus signs.
