how can append contents of solib-search-path?
i smothing like:
set solib-search-path $(solib-search-path):some/other/path
there isn't simple built-in way this. there 2 less simple ways, though.
the simplest of 2 ways use python scripting change setting. python easy current value , modify string.
the harder way use combination of set logging, shell, , source it. idea print current value file, rewrite file new set command, , source result.
