[Haskell] ANN: Blobs diagram editor

			Blobs diagram editor
			--------------------

We are pleased to announce the official launch of the 'Blobs' diagram
editor project.

Many people will already have seen the 'Dazzle' application presented
in a paper at the Haskell Workshop in Tallinn in October 2005.
Lots of you wanted the source code to play with, but unfortunately the
Bayesian analysis algorithms in Dazzle are proprietary, so Dazzle is
available only as a precompiled binary.

However, the authors of Dazzle, Arjan van IJzendoorn and Martijn
Schrage, have separated out the diagram editor front-end of their
application, and made it freely available to the community.  The basic
editing functionality has since been extended and improved, and now
we are throwing open the project to all potential contributors.

A diagram editor is a basic part of many different applications,
and we would like to see Blobs become a standard shared component
that allows different applications to share improvements to the GUI,
whilst retaining separate back-end algorithms that operate on the
underlying graph data structures.  The design of Blobs is therefore
open to any change which would improve its generality and suitability
for multiple re-targeting.

The code is made available in a darcs repository, and is licensed
like the wxWidgets toolkit on which it is based (i.e. LGPL, with a
special exemption permitting binary-only redistribution.)  There is a
new mailing list for contributors and users of Blobs:
