faster configuration.
I really like the idea, but I think we need to move to something much more
flexible than the current VTY data structures to make that work. The
existing VTY code is a pretty useful tool, but it has quite some limitations
and shortcomings that cannot be fixed quickly. One of its uglinesses is
how you specify the context sensitive help strings (as multi-line strings
with \n in them, part of what you pass to DEFUN). Other aspects are
that all new nodes need to be hacked into the VTY core and you cannot
define them yourself (see the NS_NODE that I have just introduced 2 days
ago).
Once those issues are resolved, the VTY code could become a standard
feature of libosmocore, and we wouldn't need to hack that code while
still implementing any command line menu structure we'd like.
