::  Traditionally, ovo refers to an ovum -- (pair wire card) -- and ova
::  refers to a list of them.  We have several versions of each of these
::  depending on context, so we do away with that naming scheme and use
::  the following naming scheme.
::
::  Every card is either an `event` or an `effect`.  Prepended to this
::  is `unix` if it has no ship associated with it, or `aqua` if it
::  does.  `timed` is added if it includes the time of the event.
::
::  Short names are simply the first letter of each word plus `s` if
::  it's a list.
