 def _read(self, fp, fpname):
 """A direct copy of the py2.4 version of the super class's _read method to assure it uses ordered dicts. Had to change one line to make it work. Future versions have this fixed, but in fact its quite embarrassing for the guys not to have done it right in the first place ! Removed big comments to make it more compact. Made sure it ignores initial whitespace as git uses tabs"""
