    :param tree: A Tree (such as RevisionTree) to export
    :param dest: The destination where the files,etc should be put
    :param format: The format (dir, zip, etc), if None, it will check the
                   extension on dest, looking for a match
    :param root: The root location inside the format.
                 It is common practise to have zipfiles and tarballs
                 extract into a subdirectory, rather than into the
                 current working directory.
                 If root is None, the default root will be
                 selected as the destination without its
                 extension.
    :param subdir: A starting directory within the tree. None means to export
        the entire tree, and anything else should specify the relative path to
        a directory to start exporting from.
    :param per_file_timestamps: Whether to use the timestamp stored in the
        tree rather than now(). This will do a revision lookup
        for every file so will be significantly slower.

    `dest` should either not exist or should be empty. If it does not exist it
    will be created holding the contents of this tree.

    :note: If the export fails, the destination directory will be
           left in an incompletely exported state: export is not transactional.
