flushend – Balancing columns at last page

LaTeX's built-in two-col­umn code fin­ishes off a doc­u­ment ex­actly where the text stops; this will typ­i­cally leave an iso­lated left-hand col­umn, or a right-hand col­umn shorter than the left-hand one. This pack­age mod­i­fies the LaTeX out­put rou­tine to make the two columns as nearly of the same length as pos­si­ble.
The pack­age is part of the st­tools bun­dle.
