+# B.Simon	28-Feb-89	Original

+# B.Simon	16-Jul-98	Revised to flag unparsable sections
+# B.Simon	02-Oct-98	added call to tp_count
+# B.Simon	26-Apr-99	check for data in extension zero
+# B.Simon	06-May-99	set index to one for new files w/o sections
+# B.Simon	14-Jun-99	set count to one if section could not be parsed
+# B.Simon	20-Nov-00	get default extension with iki_access
