\description{
  Internal name space support functions.  Not intended to be called directly.
}
\details{
  \code{packageHasNamespace} does not indicate if the package has a
  namespace, rather if it has a \file{NAMESPACE} file, which \code{base}
  does not.  But then you are not intended to be using it \dots.
