# Notes:
#  This EXTFS exposes buckets as directories and keys as files
#  Due to EXTFS limitations all buckets & keys have to be read initially which might
#  take quite some time.
#  Tested on Debian with Python 2.4-2.6 and boto 1.4c and 1.6b
#    (Python 2.6 might need -W ignore::DeprecationWarning due to boto using
#    deprecated module Popen2)
#
#
# Installation:
#  Make sure that boto <http://code.google.com/p/boto> (python-boto in Debian) is installed.
#  Preferably pytz (package python-tz in Debian) should be installed as well.
#
#  Save as executable file /usr/libexec/mc/extfs/s3 (or wherever your mc expects to find extfs modules)
#
# Settings: (should be set via environment)
#  Required:
