    """
    There is a collision between the `chia` file name (which is the executable)
    and the `chia` directory, which contains non-code resources like `english.txt`.
    We move all the resources in the zipped area so there is no
    need to create the `chia` directory, since the names collide.

    Fetching data now requires going into a zip file, so it will be slower.
    It's best if files that are used frequently are cached.

    A sample large compressible file (1 MB of `/dev/zero`), seems to be
    about eight times slower.

    Note that this hack isn't documented, but seems to work.
