Hans, after reading "Updating to Beta Builds of ConTeXt / LuaTeX from tlcontrib breaks MacTeX" and http://tex.stackexchange.com/questions/5405/switching-to-context-minimals-mi... I have realized that there is almost a sigle file under ConTeXt documentation in TeX Live: /usr/local/texlive/2010/texmf-dist/doc/context/document/general/manuals/tiptrick.pdf And that single file contains outdated information about how to update and how to generate formats. It might make sense to change at least that single file with completely misleading information to something that would make at least some sense. Mojca
