When bigger than zero, Vim will give messages about what it is doing. Currently, these messages are given:

= 1 When the viminfo file is read or written. = 2 When a file is ":source"'ed. = 4 Shell commands. = 5 Every searched tags file and include file. = 8 Files for which a group of autocommands is executed. = 9 Every executed autocommand. = 11 Finding items in a path = 12 Every executed function. = 13 When an exception is thrown, caught, finished, or discarded. = 14 Anything pending in a ":finally" clause. = 15 Every executed Ex command from a script (truncated at 200 characters). = 16 Every executed Ex command.

This option can also be set with the "-V" argument. See -V. This option is also set by the :verbose command.

When the 'verbosefile' option is set then the verbose messages are not displayed.
