base/str.hh:
this should really be inline
base/time.cc:
base/time.hh:
clean up how the time class works. Export only one, and let
people calculate their own elapsed times, etc.
sim/main.cc:
sim/sim_time.X -> base/time.X
--HG--
rename : sim/sim_time.cc => base/time.cc
rename : sim/sim_time.hh => base/time.hh
