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