[NTG-context] unknown script 'context.lua' or 'mtx-context.lua'

Hans, why don't you add a special-case in this case:

context test MTXrun | unknown script 'context.lua' or 'mtx-context.lua'

if 'context.lua' cannot be found then either: a) instead of printing out "unknown script 'context.lua'" print out "please run 'luatools --generate'" - it will be less confusing for users b) or (may be even better) try to run "luatools --generate" automatically and then retry I guess that there is some not-too-difficult way to figure out from within mtxrun that no database exists yet.
