  \code{getExportedValue} returns the value of the exported variable
  \code{name} in namespace \code{ns}.

  \code{getNamespace} returns the environment representing the name
  space \code{name}.  The namespace is loaded if necessary.

  \code{getNamespaceExports} returns a character vector of the names
  exported by \code{ns}.

  \code{getNamespaceImports} returns a representation of the imports
  used by namespace \code{ns}.  This representation is experimental
  and subject to change.

  \code{getNamespaceName} and \code{getNamespaceVersion} return the name
  and version of the namespace \code{ns}.

  \code{getNamespaceUsers} returns a character vector of the names of
  the namespaces that import namespace \code{ns}.
