Module Functions:

							*perl-Msg*
VIM::Msg({msg})
			Displays the message {msg}.

							*perl-SetOption*
VIM::SetOption({arg})	Sets a vim option.  {arg} can be any argument that the
			":set" command accepts.  Note that this means that no
			spaces are allowed in the argument!  See |:set|.

							*perl-Buffers*
VIM::Buffers([{bn}...])	With no arguments, returns a list of all the buffers
			in an array context or returns the number of buffers
			in a scalar context.  For a list of buffer names or
			numbers {bn}, returns a list of the buffers matching
			{bn}, using the same rules as Vim's internal
			|bufname()| function.
			WARNING: the list becomes invalid when |:bwipe| is
			used.

							*perl-Windows*
VIM::Windows([{wn}...])	With no arguments, returns a list of all the windows
			in an array context or returns the number of windows
			in a scalar context.  For a list of window numbers
			{wn}, returns a list of the windows with those
			numbers.
			WARNING: the list becomes invalid when a window is
			closed.

							*perl-DoCommand*
VIM::DoCommand({cmd})	Executes Ex command {cmd}.

							*perl-Eval*
VIM::Eval({expr})	Evaluates {expr} and returns (success, value) in list
			context or just value in scalar context.
			success=1 indicates that
