/*
* DESCRIPTION:
* This module produces Global IME for Vim, on Windows with Internet
* Explorer 5.01 or higher. You need three files "dimm.idl", "dimm.h", and
* "dimm_i.c" when compile this module at your self. "dimm.h", and
* "dimm_i.c" are generated from "dimm.idl" by using MIDL.EXE as like
* "if_ole.h". You can get "dimm.idl" in MSDN web site. I got it below
* URL.
*
* WHAT IS THE GLOBAL IME?:
* Global IME makes capability input Chinese, Japanese, and Korean text into
* Vim buffer on any language version of Windows 98, Windows 95, and Windows
* NT 4.0. See below URL for detail of Global IME. You can also find
* various language version of Global IME at same place.
*
* RUNTIME REQUIREMENTS:
* - Internet Explorer 5.01 or higher.
* - Global IME (with language pack?).
* - Of course Vim for Windows.
*
* URLS:
* - Where you can probably get "dimm.idl".
* http://msdn.microsoft.com/downloads/samples/internet/libraries/ie5_lib/sample.asp
* - Global IME detailed information.
* http://www.microsoft.com/windows/ie/features/ime.asp
