  The current work reports the development of a new general grid generator
called Gingred for arbitrary (e.g., number of X-points) 2D magnetic equilibria
and plate geometries. A standardization of the construction of a grid is
explained, the main command lines are detailed, and examples of snowflake grids
are shown. The main advantages of Gingred are the tracking of the step-by-step
progresses (from "skeleton" grids) of grid generations by non-experts and new
users, the ability to use an arbitrary magnetic configuration, and the more
accurate numerical computation by bi-cubic interpolation of the magnetic flux
rather than discrete cosine transform.
