Yes, but that has led to a very heterogeneous default library cluttered =
with obsolete symbols. At the same time, it=92s a bit clumsy to import =
from the even more heterogeneous but often more useful gedasymbols =
hierarchy.
My approach is to maintain a project-specific symbol library with shell =
commands. That also works, but I think graphical objects really deserve =
a graphical browser. I see this as separate from gschem: library =
maintenance as opposed to schematic capture using that library.
