It would indeed be interesting to have a comparison table of features
in one place.  Then we could try to figure out what we want to
support.  I'm guessing no single tool in its current form will do.

I can help with the little I know:

  . etags includes support for many languages (see the list at the end
    of what "etags --help" displays), including some "languages", like
    HTML, which aren't really programming languages.  However, support
    for some of the languages is very basic.  Also, etags is only
    partially useful for C++.

  . ebrowse supports C++, but it wasn't updated for new C++ features
    in a very long time, so it probably is not really up to job

For inclusion in Emacs, we should also consider whether it will be
possible to get copyright assignment from the contributors.
