I also believe something like this, yes.

I usually tag the toplevel dirs separately (or better the big, active
ones, i.e. libjava/, libstdc++-v3/, gcc/).  Then a local (-l) tag of the
toplevel dir, and then all the other toplevel dirs together.  Sometimes if
gcc/ takes too long I repeat a similar process inside the gcc directory
(tagging it without recursing, then all subdirs of it separately).  This
works much better than tagging the whole tree at once.


Ciao,
Michael.
