dlocate and grep-dctrl for example.

interestingly, 'apt-cache show' is even faster than dlocate (which makes
use of grep-dctrl to do the search).

$ time apt-cache show dpkg >/dev/null
real    0m0.235s
user    0m0.210s
sys     0m0.030s

$ time dlocate -s dpkg>/dev/null
real    0m0.407s
user    0m0.380s
sys     0m0.010s

$ time dpkg -s dpkg>/dev/null
real    0m1.517s
user    0m1.410s
sys     0m0.100s
