The section on ConTeXt anticipated the planned move from ConTeXt
mkiv + mkii to lmtx + mkiv within TL. This move is now a fact, and
'mtxrun --generate' and 'context --luatex --generate' should now
work as advertised. It is still not quite settled if or when these
commands should be run manually by the user.
