[pstricks] info about \psCumIntegral

[Carlo Alberini]

Dear Alexander, 
	thank you for your mail; I think about a function like:

$\int_{2x+3}^{\frac{1}{x+1}}f(t)dt$, with some f(t) as you like. 

It would be fantastic if I could have the plot af such a function… written with the “algebraic” option (easy and fast …)

Thank you
Carlo
