    A versioned file manages versions of line-based text files,
    keeping track of the originating version for each line.

    To clients the "lines" of the file are represented as a list of
    strings. These strings will typically have terminal newline
    characters, but this is not required.  In particular files commonly
    do not have a newline at the end of the file.

    Texts are identified by a version-id string.

            children.
        :param include_delta_closure: If True then the closure across any
            compression parents will be included (in the data content of the
            stream, not in the emitted records). This guarantees that
            'fulltext' can be used successfully on every record.

        Must raise RevisionNotPresent if any of the given parents are
        not present in file history.

        :param lines: A list of lines. Each line must be a bytestring. And all
            of them except the last must be terminated with 
 and contain no
            other 
's. The last line may either contain no 
's or a single
            terminated 
. If the lines list does meet this constraint the add
            routine may error or may succeed - but you will be unable to read
            the data back accurately. (Checking the lines have been split
            correctly is expensive and extremely unlikely to catch bugs so it
            is not done at runtime unless check_content is True.)
        :param parent_texts: An optional dictionary containing the opaque
            representations of some or all of the parents of version_id to
            allow delta optimisations.  VERY IMPORTANT: the texts must be those
            returned by add_lines or data corruption can be caused.

            between the text and its left-hand-parent.  The format is
            the SequenceMatcher.get_matching_blocks format.
        :param nostore_sha: Raise ExistingContent and do not add the lines to
            the versioned file if the digest of the lines matches this.
        :param random_id: If True a random id has been selected rather than
            an id determined by some deterministic process such as a converter
            from a foreign VCS. When True the backend may choose not to check
            for uniqueness of the resulting key within the versioned file, so
            this should only be done when the result is expected to be unique
            anyway.

            bytestrings that are correctly formed lines.

    This object allows a single keyspace for accessing the history graph and
    contents of named bytestrings.

    Currently no implementation allows the graph of different key prefixes to
    intersect, but the API does allow such implementations in the future.

    The keyspace is expressed via simple tuples. Any instance of VersionedFiles
    may have a different length key-size, but that size will be constant for
    all texts added to or retrieved from it. For instance, bzrlib uses
    instances with a key-size of 2 for storing user files in a repository, with
    the first element the fileid, and the second the version of that file.

    The use of tuples allows a single code base to support several different
    uses with only the mapping logic changing from instance to instance.

        this is a list of other VersionedFiles immediately underneath this
