Page from a GFDL-licensed web page[edit]
This article was originally at [1], which has been released under the GFDL (actually, it's dual-licensed with an "all rights reserved", which I understand is fine). The article still needs some edits to bring it to an encyclopedic, formal tone. delldot ∇. 15:48, 10 June 2010 (UTC)
