The triptest is only there to help you determine that your implementation is okay. you are neither allowed to fix bugs or add extra features (new commands, or whatever). theroretically (now Goedel turns up again:-) a program is only allowed to call itself TeX if it produces for all inputs exactly the same output compared to the master copy in stanford (there are technically a bunch of exceptions related to floating point stuff in dvi production, but that isn't related to the argument. have a look at Don's home page. there you find that upon his death TeX version number goes up to \pi and from there on all bugs are by definition features. of course you are allowedto rename the source files and produce whatever you wish from them, but you are not allowed to call the resulting thing "TeX" again not even if you have the most valid bug fix upon your sleave. frank
