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 * Coordinates input/output to/from backend. Each MMBackend communicates
14 * directly with a MMVimController.
16 * MMVimController does not deal with visual presentation. Essentially it
17 * should be able to run with no window present.
19 * Output from the backend is received in processCommandQueue:. Input is sent
20 * to the backend via sendMessage:data: or addVimInput:. The latter allows
21 * execution of arbitrary strings in the Vim process, much like the Vim script
22 * function remote_send() does. The messages that may be passed between
23 * frontend and backend are defined in an enum in MacVim.h.
