# Allow users to override the namespace we define our application's classes in
# Arg $1 is the default namespace to use if --enable-namespace isn't present.
# In general, $1 should be 'google', so we put all our exported symbols in a
# unique namespace that is not likely to conflict with anyone else. However,
# when it makes sense -- for instance, when publishing stl-like code -- you
# may want to go with a different default, like 'std'.
