# Module 'stat'

# Defines constants and functions for interpreting stat/lstat struct

# as returned by os.stat() and os.lstat() (if it exists).

# Suggested usage: from stat import *

# XXX Strictly spoken, this module may have to be adapted for each POSIX

# implementation; in practice, however, the numeric constants used by

# stat() are almost universal (even for stat() emulations on non-UNIX

# systems like Macintosh or MS-DOS).

# Indices for stat struct members in tuple returned by os.stat()
