5 * Do ":help uganda" in Vim to read copying and usage conditions.
6 * Do ":help credits" in Vim to see a list of people who contributed.
7 * See README.txt for an overview of the Vim source code.
11 * ops.c: implementation of various operators: op_shift, op_delete, op_tilde,
12 * op_change, op_yank, do_put, do_join
