6 * Do ":help uganda" in Vim to read copying and usage conditions.
7 * Do ":help credits" in Vim to see a list of people who contributed.
8 * See README.txt for an overview of the Vim source code.
13 * A view class with a tabline, scrollbars, and a text view. The tabline may
14 * appear at the top of the view in which case it fills up the view from left
15 * to right edge. Any number of scrollbars may appear adjacent to all other
16 * edges of the view (there may be more than one scrollbar per edge and
17 * scrollbars may also be placed on the left edge of the view). The rest of
18 * the view is filled by the text view.
