+# Modified April 9, 2004 by Leann Ogasawara <ogasawara@osdl.org>
+#  - expanded @tests array to add more symlinks and permissions tests
+#  - some of the symlinks tests also test lack of node creation
+#  - added symlink_test() function
+#  - moved permissions and major_minor tests into their own functions
