Thanks. The DE acronym was used by it's originator, I've just used it

It's not that hard. You just have to express your wishes as math

* I'd like to have ice-cream

> PS. Werner.. do you want me to send you the .spec file for xgsch2pcb?
Yes of course. 
Will xgsch2pcb work with all the tools release with the gEDA 1.2.0
