In my git head copy of gschem a file chooser dialog launches if I
select file->Execute_script.. But fair enough. I put the guile
commands into a file.

The script did place a resistor on the page. But unlike a symbol
placed via the GUI no attributes got promoted and instantiated in the
schematic. The refdes rendered in red and were not editable.
I tried to promote the refdes attribute manually via the context menu
in the attribute editor. This produced a promoted copy of the
attribute at some default position, not identical to the position
given to the refdes in the *.sym file. The unpromoted version of the
refdes attribute remained visible.

Err, well ... this is well hidden.
How should I know that "geda-scheme" is the term to look for in info?
There is no info node for gschem so info defaults to the man page. The
man page does not mention scheme at all. It is quite brief and refers
the reader to "the program's `Help' menu.". The help menu of gschem
opens an offline copy of
http://wiki.geda-project.org/geda:documentation
(BTW, the file characterizes itself as "on-line documentation".
Somebody with write access to the wiki might remove the attribute "on-
line" to make the heading compatible for offline use, too)
Unlike the on-line version of the wiki, the static HTML pages do not
offer a search facility. But let's assume I was smart enough to browse
to the "gEDA gschem User guide". (BTW, wouldn't it be nice to refer
the user directly to the manual in the first place?) The very last
section of the manual is "Appendix: Extending gschem". This section
focuses on ways to change gschem itself not on ways to change the
schematic.
It says: "The gEDA Scheme Reference Manual is **also** available as an
Info manual (info geda-scheme)." (emphasis by me)
I did not find any other place for the geda scheme references than the
info page. Did I miss something again?
Anyway, I got the good news:
Scripted manipulation of schematics works -- sort of.
