(name, a)
return rv(name, MaxwellDistribution, (a, ))
r"""
    Create a continuous random variable with a Maxwell distribution.

    The density of the Maxwell distribution is given by

    .. math::
        f(x) := \sqrt{\frac{2}{\pi}} \frac{x^2 e^{-x^2/(2a^2)}}{a^3}

    with :math:`x \geq 0`.

    .. TODO - what does the parameter mean?

    Parameters
    ==========

    a : Real number, `a > 0`

    Returns
    =======

    A RandomSymbol.

    Examples
    ========

    >>> from sympy.stats import Maxwell, density, E, variance
    >>> from sympy import Symbol, simplify

    >>> a = Symbol("a", positive=True)
    >>> z = Symbol("z")

    >>> X = Maxwell("x", a)

    >>> density(X)(z)
    sqrt(2)*z**2*exp(-z**2/(2*a**2))/(sqrt(pi)*a**3)

    >>> E(X)
    2*sqrt(2)*a/sqrt(pi)

    >>> simplify(variance(X))
    a**2*(-8 + 3*pi)/pi
