Ahoy Mike,
Here's the short story: It's called a jack line and it allows the sail to come down without a need for loosening the clew/outhaul. Once adjusted, the line is tied off tight at the tack.
This is the long story: The LP (luff perpendicular) of the staysail is shorter than the foot length. The clew represents both one end of the LP and one end of the foot. If the clew is fixed in position then the luff of the sail cannot move further away as would be necessary when the sail is lowered. The sail will bind when the halyard is slackened and not come down - unless the clew is loosened. The jack line, when properly adjusted, has the effect of allowing the luff to move closer to the clew on it's way down. This whole affair is usually preferable to always having to loosen then re-tension the clew/outhaul.
