You don't have to have a list of every single function, the most common will do - but of course, the more complete the list, the better... But how do you find out? Before you told me, I didn't know `append' was linear. Do you examine the code and do analysis? If so, I'll pass this project :) -- underground experts united http://user.it.uu.se/~embe8573
