I managed to install the greek module. Here is where it is placed: adsm@adsm:/etc/texmf/tex/context/third> ls t-ancientgreek adsm@adsm:/etc/texmf/tex/context/third> cd t-ancientgreek/ adsm@adsm:/etc/texmf/tex/context/third/t-ancientgreek> ls fonts t-ancientgreek.mkiv t-oldgreek.tex type-agr.mkiv t-ancientgreek.mkii t-ancientgreek.tex type-agr.mkii type-agr.tex adsm@adsm:/etc/texmf/tex/context/third/t-ancientgreek> adsm@adsm:~> kpsewhere t-ancientgreek.tex /etc/texmf/tex/context/third/t-ancientgreek/t-ancientgreek.tex The point now is that I need to build the fonts (or build the metric =20 files of the fonts). So need to use texfont, am I right? One mandatory =20 argument is the vendor's name. Which name should I type for GFSDidot, =20 GFSPorson, Ibycus, Gentium? Another issue: Xetex says repeatedly (as you can see on the attached file) ! Undefined control sequence. l.5 \beginOLDTEX I ask if there is no compatibility between Xetex and greekmodule can I =20 use Context with unicode (utf8) input (the manual which I suppose is =20 quite outdated says Context expects pure ASCII input)? Thanks for your help. Armando Martins
