Creating GFD files - Manual/Script/Designer

Reinhard/anyone: how do you create GFD files currently?
By hand in a text editor, only - or with the help of some script?
[sorry if this was already answered; i do not see record in gnue-dev archive
of recent months, and irc-logs are empty since 2010-09.]

One of my thoughts, which I had not yet spelled out on the maillist, is
a command-line script to generate a basic GFD file from a schema, like
what we would expect from the Designer wizard/druid.
(I see something about gnue-schema, which generates schema SQL-DDL from XML,
but I'm more interested in the other way around, generate GFD-XML from
schema.)

Purpose of such script would be two-fold:
 * useful on its own, before getting Designer up & running, maybe still after;
 * unit test or proof of concept of code to be adaptable for Designer.

Strategy of such script would be as follows:
1. adapt portions of legacy Designer (0.5) wizard to a command-line script,
   but generate new-style hbox/vbox GFD rather than legacy x-y GFD.
2. adapt generation of hbox/vbox GFD from script to Designer.
