11 * MMBackend
12 *
13 * MMBackend communicates with the frontend (MacVim). It maintains a queue of
14 * output which is flushed to the frontend under controlled circumstances (so
15 * as to maintain a steady framerate). Input from the frontend is also handled
16 * here.
17 *
18 * The frontend communicates with the backend via the MMBackendProtocol. In
19 * particular, input is sent to the backend via processInput:data: and Vim
20 * state can be queried from the frontend with evaluateExpression:.
21 *
22 * It is very important to realize that all state is held by the backend, the
23 * frontend must either ask for state [MMBackend evaluateExpression:] or wait
24 * for the backend to update [MMAppController processInput:forIdentifier:].
25 *
26 * The client/server functionality of Vim is handled by the backend. It sets
27 * up a named NSConnection to which other Vim processes can connect.
