 The first argument provides signature specifications, the second argument is the variable name for the `TensorBundle`, and the third and fourth argument are the the prefixes of the `SubManifold` vector names (and covector basis names). By default, `V` is assigned the `TensorBundle` and `v` is the prefix for the `SubManifold` elements.
 
 It is entirely possible to assign multiple different bases with different signatures without any problems. In the following command, the `@basis` macro arguments are used to assign the vector space name to `S` instead of `V` and basis elements to `b` instead of `v`, so that their local names do not interfere.
-Alternatively, if you do not wish to assign these variables to your local workspace, the versatile `DirctSum.Basis` constructors can be used to contain them, which is exported to the user as the method `Λ(V)`.

 The parametric type formalism in `Grassmann` is highly expressive to enable the pre-allocation of geometric algebra computations for specific sparse-subalgebras, including the representation of rotational groups, Lie bivector algebras, and affine projective geometry.
