[NTG-context] Documentation

Hi! First, sorry to have sent the previous message twice. I didn't check for the sending email, received a bounce, resent to discover it passed to the list. I have downloaded a great part of the documentation (59 files or so). But if I understood well, there has been big changes between Mark II and Mark IV/Lua. The documentation seems more linked to MkII. Is mk.pdf the file to use (in conjonction with another?)? I like cont-eni.pdf but I'd like to have it as print not to be seen on screen (old habit of work - or habit of work of old!!)
