# A class representing the attributes of a file or directory on the server.
# It may be used to specify new attributes, or to query existing attributes.
# This particular class is specific to versions 4 and 5 of the SFTP
# protocol.
#
# To specify new attributes, just pass a hash as the argument to the
# constructor. The following keys are supported:
#
# * :type:: the type of the item (integer, one of the T_ constants)
# * :size:: the size of the item (integer)
# * :uid:: the user-id that owns the file (integer)
# * :gid:: the group-id that owns the file (integer)
# * :owner:: the name of the user that owns the file (string)
# * :group:: the name of the group that owns the file (string)
# * :permissions:: the permissions on the file (integer, e.g. 0755)
# * :atime:: the access time of the file (integer, seconds since epoch)
# * :atime_nseconds:: the nanosecond component of atime (integer)
# * :createtime:: the time at which the file was created (integer, seconds since epoch)
# * :createtime_nseconds:: the nanosecond component of createtime (integer)
# * :mtime:: the modification time of the file (integer, seconds since epoch)
# * :mtime_nseconds:: the nanosecond component of mtime (integer)
# * :acl:: an array of ACL entries for the item
# * :extended:: a hash of name/value pairs identifying extended info
#
# Likewise, when the server sends an Attributes object, all of the
# above attributes are exposed as methods (though not all will be set with
# non-nil values from the server).
