Dear ConTeXt-ers, I am using protrusion and char. expansion for a book project (with MKIV from the latest ConTeXt minimal), and it works wonderfully, with the exception of a minor problem: I find the preset protrusion parameters for "guillemets" (double angle quotes) which occur frequently in my (Italian) text too large, and would like to modify them. Relying on the wiki and mailing-list posts, I realised that the parameters are set in the file font-ext.lua, but changing this file seems to have no effect on the typesetting. How should I rebuild/recompile ConTeXt in order to "apply" my changes? I am a novice ConTeXt user, so please forgive me if my question is trivial. Thanks in advance for your help and best wishes, András Simonyi, Budapest, Hungary
