+
+                dict GetEntry(object path)
+
+                        Returns properties for the profile entry. The
+                        following read-only properties are returned:

+                                Auto-connection setting.
+
+                        string Failure [readonly]
+                                Reason for last failure.
+
+                        string Modified [readonly]

+
+                dict DeleteEntry(object path)

+                        Removes the entry from the profile.  Any associated
+                        service has its security credentials revoked but
+                        is otherwise unaffected (i.e. it will remain connected).
