well, simply changing only the author to ck is also a bad idea... simply compare the code the SML-1.0 and you'll see what he did. So at least some sort of "based on SML-1.0 by Elkano" should be included I think.
both Libstub and CallBackHandler-1.0 have been decided on to have to be included by the addon using the lib but are hardcopied into the lib currently because of the way WAU works currently. since if you run eg LSM-3.0 standalone you'll need these two but they are both not intended to be run standalone themself. But WAU would remove them from the lib if it's set to disembedded.
