def create_cmdclass(prerelease_cmd=None, package_data_spec=None,
        data_files_spec=None):
    """Create a command class with the given optional prerelease class.

    Parameters
    ----------
    prerelease_cmd: (name, Command) tuple, optional
        The command to run before releasing.
    package_data_spec: dict, optional
        A dictionary whose keys are the dotted package names and
        whose values are a list of glob patterns.
    data_files_spec: list, optional
        A list of (path, patterns) tuples where the path is the
        `data_files` install path and the patterns are glob patterns.

    Notes
    -----
    We use specs so that we can find the files *after* the build
    command has run.

    The package data glob patterns should be relative paths from the package
    folder containing the __init__.py file, which is given as the package
    name.
    e.g. `dict(foo=['./bar/*', './baz/**'])`

    The data files glob patterns should be absolute paths or relative paths
    from the root directory of the repository.
    e.g. `('share/foo/bar', ['pkgname/bizz/*', 'pkgname/baz/**'])`
