Someone suggested, on the python list, to take a look again at cscope,
because it can be used as a general purpose text indexer. And indeed
it can, but I found idutils of more "comfortable" use, apparently
easier to extend to other languages, and I really like how idutils
displays the results under Emacs. And I got the impression that
although cscope is still very much used, it is no longer actively
developed.So for now, I'll keep looking at idutils.

Thanks! I didn't know that. (This is interesting because the other
night I found, on the exuberant ctags patch list, a patch to scan R
files by Stefan Archer;
 I haven't tried it yet, though).
