ok, i will add a fake

best make a

yourmodule.tex
yourmodule.mkii
yourmodule.mkiv

and in the tex file adds:

\loadmarkfile{yourmodule}

ok, another fake

well, that everything now can be 'textext'

hm, so \sometxt is not working? i thought that i tested it (maybe not 
... too much to test)

i think that we have it in the core


anyhow, just collects what does not work

(btw, i fixed something in textext ... i used to work only for code 
passed as mpgraphic, but now it works also with libraries and so)
