Gerald, I will be glad to translate the

today. Next weekend maybe. Is that fine?
Mateusz, as you are a pogrammer could you take care of
Frank, if Gerald makes it to include this correction in liproj, do you
think you could port it to PROJ.4 then?

I remember. I also remember I wasn't able to help you much then. I was
an absolute newbie to GIS and projections. Since then I've learned
enough, I hope, to be some helpfull in regard of Polish grids now. I
think we can sort out the "System 65" issue together finally.

Right, sterea is a very good match when compared to reference Transpol
1.1. I'd love to compare it to rouss too, if it is going to be ported to
Frank's PROJ.4. Is it?
Thanks to you all.
