Yes and no. To the best of my knowledge, though I could be wrong:
- Lepton is a fork of gEDA.
- xorn is maybe partly a fork or a reimplementation using a new core
for gEDA. I think some elements of the xorn netlist are back inside
gEDA itself, but I can't be sure of that. Someone who knows can say.
- pcb is an old tool not formally part of gEDA (afaik) but closely
associated with it.
- pcb-rnd is a fork of pcb.

In general, I would agree with you. In this case, however, due to the
fact that (atleast so far) they all use compatible file formats, and
the forks are still 'fresh', there is value to the user knowing that
these are related software.

I think there is one. At any rate, installation on 20.04 is only a
matter of apt install lepton-eda. When I was 'migrating', however, I
did hit some issues regarding the configuration. These were resolved
fairly easily over a short conversation on the gitter, and was due to
some ambiguity in the text of the documentation I was following. I
suggested a clarification to it and was told it would be added, but I
will admit I didn't follow up on it afterwards.
I believe the documentation I was following was
https://github.com/lepton-eda/lepton-eda/wiki/Configuration-Settings

Could'nt the tutorial pretty easily be produced on basis of the gsch2pcb tutorial by changing some file- and command names?

Older ubuntu versions came with an outdated gEDA in the repositories so I've been compiling gEDA from release source tarballs and git for quite some time now, but after about a half hour of dealing with dependencies and the build still failing I just gave up and decided to use lepton.

The side panels are pretty useless as they stand now to have permanent residence on a big portion of the screen. Gschem did go through that same phase, which was when I started using the git head more regularly once they cleaned up that side panel layout and made it more useful. It would be nice if lepton could do something about it as well.

My suspicion is that the fork which is able to keep distribution packages and installers updated will be the one that wins out. We're already talking about investigating the use of kicad, even though we have a number of hand rolled tools which specifically depend on the much friendlier file format of gschem.

With gEDA I could install it by a simple statement or a click in Ubuntu programs and I had access to a very good tutorial. Now I have spent 4 days installing Lepton-eda and I am not finished yet and there is no tutorial. I am also left with the feeling that the Lepton-eda project is in trouble. Is there an authorised version of Lepton-eda? Is there a tutorial coming? What is Ubuntu's role now? Does gEDA still exist and being maintained?
