Hi all, It is my first mail to this list. I am using XeTeX and XeTeX + ConTeXt environment for my most files for sometime. It worked fine and the output is really great. I'd like to use it to create a presentation instead of using LaTeX + beamer. I have seen many output samples of the presentation styles like s-pre-#.tex. But I didn't find how to use it in the ConTeXt manual. Recently, I googled and found some files for presentation including Hraban's source, but I didn't succeed. I try to compile it in the pure ConTeXt environment, texexec --pdf project_pdf-info.tex and got some error messages. ..... bodyfont : bodyfont 16pt is defined (can better be done global) bodyfont : bodyfont 16pt is defined (can better be done global) system : macros of module chart loaded (/usr/local/teTeX/share/texmf.local/tex/context/base/m-chart.tex XML : loading flowchart support )) systems : end file env_pdf-info at line 3 systems : begin file prd_grundlagen at line 46 (./prd_grundlagen.tex ! Undefined control sequence. \StartTitlePage ...lign [right] \stelinterliniein \vfil \let \\=\vfil l.4 \StartTitlePage ? x No pages of output. ..... Now I am using OS X 10.3.8 and Gerben's installation. What should I do to remove this error? Is there any place or samples to show "how to create presentation"? I am sorry if it is too well known subject. Regards, Dalyoung
