/*
 * 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
