For those who don’t know, [GEOS](http://geos.refractions.net/) is an open source C++ library that contains a lot of functionality for analyzing and manipulating geometries. It is also one of the key parts of [PostGIS](http://postgis.refractions.net/). [Sandros](http://foo.keybit.net/~strk/) and [Mateusz](http://mateusz.loskot.net/2006/04/06/say-hello-to-geos-development-team/) have been doing a ton of refactoring and adding functionality in preparation for a Geos 3.0 release (no date yet determined).

Besides providing a C and C++ api, there are also Python and Ruby bindings (the [Ruby bindings](http://cfis.savagexi.com/articles/2006/04/12/ruby-bindings-for-geos) will be new with the upcoming 2.2.2 release). This is the bit I now maintain. So check it out, and any ideas/suggestions are welcome – send them to the [geos-devel](http://geos.refractions.net/mailman/listinfo/geos-devel) list.

Thanks to Sean, Sandro and [Paul](http://geotips.blogspot.com/) for setting this up.
