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