3 * VIM - Vi IMproved by Bram Moolenaar
4 * MacVim GUI port by Bjorn Winckler
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 * Dispatches keyboard and mouse input to the backend. Handles drag-n-drop of
16 * Support for input managers is somewhat hacked together. Marked text is
17 * displayed in a popup window instead of 'in-line' (because it is easier).
