Announcing the release of a new library for Haskell: Partial v0.1 The Partial library provides a partial order class. It also provides routines for generating a Hasse diagram from a set and a partial order. Renderers are provided for the abstract Hasse diagram representation into LaTeX (via Xy-pic) and into dot, the format for AT&T's Graphviz tools. Since no horizontal sorting is done, the Xy-pic output is rather poor at present; dot does a much better job with its layout optimisation algorithm. Available from: http://www.cl.cam.ac.uk/users/kw217/libs/ I hope someone finds this useful! --KW 8-)
