Hi,
  It's difficult to read source code, for its comment is 
not English and there is no other development document. 
More worse, I can't compile it under VC++ 6, there are up 
to hundreds of errors.
  Here are some suggestions:
    1. write comments in English.
    2. provide some documents about development, 
introducing the architecture of source code, compiling 
HOWTO.
    3. make it easier for novice to compile.
