Some personal information If there is no response to your email for some time .. Note: Because of massive amounts of work pending, responses to any kind of correspondence may be significantly delayed (actually so significantly that I think this note is required - don’t wonder or worry if it should take months in some cases). Nevertheless, your input is appreciated. Also, updates of these webpages are still in slow mode with a long queue of stuff waiting to be worked in; sorry for any inconveniences this may cause. © 1995 to current Spider ( Hartmut Frommert ) at SEDS ... but free for non-profit use ...
