What is -- Fractional integro-differentiation

 Fractional integro-differentiation is discussed at  
 http://functions.wolfram.com/ElementaryFunctions/Power/20/03/
 
 I never herd of this.  
 Is this where we compute something like  D[f[x],{x,1/2}].  
 If yes, what is the definition of such a thing?  
 I always assumed the (n) in D[f[x],{x,n}] had to be an Integer.

 Thanks,
