你说的那两个地方我看到了,而且里面还说,
The .ifo file has the following format:
StarDict's dict ifo file
version=2.4.2
[options]
Note that the current "version" string must be "2.4.2" or "3.0.0".If it's not,
then StarDict will refuse to read the file.
If version is "3.0.0", StarDict will parse the "idxoffsetbits" option.
估计version 3.0.0的话会有不同的地方。但是他并没有注明idxoffsetbits里的new option 是什么。
