Hi, although the following is an announcement of a pure MetaPost library, I thought that it might be of interest to this list, given the tight integration of MetaPost with ConTeXt. Metappeal is an extension to Plain MetaPost, providing a lightweight framework for consistent development in MetaPost. Metappeal 0.1.0 is the second release of this newborn project, bringing you new prominent features: - classes and templates; - delegation; - new basic data structures (bigints, bigstrings); - much better documentation (which is different from "very good documentation"). in addition to a unit testing framework, other data structures (arrays, records, stacks, lists, trees, mboxes, ...) and parametrized code blocks. Nothing graphical yet, sorry, apart from mboxes (getting classes right was hard enough). Metappeal is available from: http://users.dimi.uniud.it/~nicola.vitacolonna/home/content/metappeal and feedback is welcome. Happy MetaPost development! Nicola
