That is roughly how far I got but gschem "forgot" the entries after a
while. Then I tried it again with a dual opamp. In order not to mess up
too badly with a new CAD system I start with existing symbols and modify
them. With the dual opamp my changes stuck. Well, to some extent (it
forgot the slotdef changes after I copied that very same symbol).
Now I am going to have to figure out how to make gschem find it in the
menu. Eagle had a preferences menu that let you set directory paths. You
could set that to a personal area, copy all the libs to that and then
piece by piece replace things with your own symbols and footprints.
I guess that steep learning curve must be tackled ...

Thanks. It is nice that we can attach small pics here. In usenet groups
that doesn't work any more after some Attorney general went overzealous :-(
