+# Module 'stat'
+
+# Defines constants and functions for interpreting stat/lstat struct
+# as returned by posix.stat() and posix.lstat() (if it exists).
+
+# XXX This module may have to be adapted for UNIXoid systems whose
+# <sys/stat.h> deviates from AT&T or BSD UNIX; their S_IF* constants
+# may differ.
+
+# Suggested usage: from stat import *
+
+# Tuple indices for stat struct members
