Such bundling the defact library process may cause too late to change APIs on bundling it. I fear that the library is good for usual purpose but has critical problem for unusual purpose or environments. > BTW, I think NArray satisfies the conditions; stable enough and widely used. NArray is stable and widely used. But I belive its true value is that NArray is the library for libraries. A Bundled library should be a such library. -- NARUSE, Yui
