I made a plain TeX module for simple abbreviation and bibliography handling. The problem is it currently uses a temporary file to keep track of used bibs / abbreviations. Essentially it writes \addToList [\usedAbbreviations]{<abbr>} and \addToList[\usedReferences]{<cite>} commands to it, and this file is input on the second pass. After finding out that ConTeXt *really is* well thought of and robust I changed the functionality to use TeXutil with \writeutilitycommand. Everything seems to work, the commands appear in .tui/.tuo files and are executed, but the token lists are empty when execution reaches the document. I couldn't figure out how to fix it as I don't yet know enough about the anatomy of a ConTeXt run and the system. Jyrki Ruuskanen
