Hi all, Is there are way I can have ConTeXt halt on particular warnings or errors? In particular, I like it to spit the dummy when it finds an unknown reference. Otherwise, I end up with the unknown references in the document that I sometimes don't find until much later. At the moment I grep for "reference" when I run context, as in context *.tex | grep reference ...but I thought there might be some more elegant way to do this. Thank you, Malte. -- “The Electric Monk was a labour-saving device, like a dishwasher or a video recorder...
