# 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
