doesn't this put a copy of env_cleanser.o in both libsel and libenv_cleanser? 
why?

[Evgeniy Stepanov, 2011/05/18 19:05:05]

Did not want to include libenv_cleanser in every target than depends on libsel,
there are, like, 7 of them. Or does scons somehow keep dependencies between
static libraries?

I'm fine with doing this either way.
