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 * Contains code shared between the different text renderers. Unfortunately it
14 * is not possible to let the text renderers inherit from this class since
15 * MMTextView needs to inherit from NSTextView whereas MMAtsuiTextView needs to
16 * inherit from NSView.
