flopy.discretization.grid.Grid signature does not match docstring

[Olsthoorn]

Here is the signature

flopy.discretization.grid.Grid(grid_type=None, top=None. botm=None, idomain=None, lenuni=None, epsg=None, proj4=None, prj=None, xoff=0.0, yoff=0.0, angrot=0.0)

And here is the docstring (from the source), they are complely incompatible

class Grid(object):
"""
Base class for a structured or unstructured model grid

Parameters
----------
grid_type : enumeration
    type of model grid ('structured', 'vertex_layered',
    'vertex_unlayered')
top : ndarray(np.float)
    top elevations of cells in topmost layer
botm : ndarray(np.float)
    bottom elevations of all cells
idomain : ndarray(np.int)
    ibound/idomain value for each cell
lenuni : ndarray(np.int)
    model length units
origin_loc : str
    Corner of the model grid that is the model origin
    'ul' (upper left corner) or 'll' (lower left corner)
origin_x : float
    x coordinate of the origin point (lower left corner of model grid)
    in the spatial reference coordinate system
origin_y : float
    y coordinate of the origin point (lower left corner of model grid)
    in the spatial reference coordinate system
rotation : float
    rotation angle of model grid, as it is rotated around the origin point
