-<Func Name="CoefficientMultivariatePolynomial" Arg ="f, var, power, R"/>
-
-<Description>
-The command <C>CoefficientMultivariatePolynomial</C>
-takes four arguments: a multivariant polynomial 
-<A>f</A>, a variable name <A>var</A>, an integer
-<A>power</A>, and a polynomial ring <A>R</A> containing <A>f</A>.
-For example, if <A>f</A> is a multivariate polynomial in 
-<M>R</M> = <M>F</M>[<M>x_1,x_2,...,x_n</M>] then <A>var</A> must be
-one of the <M>x_i</M>.
-The output is the coefficient of <M>x_i^{power}</M>
-in <A>f</A>.
-<P/>
-(Not sure if <M>F</M> needs to be a field in fact ...)
-<P/>
-Related to the GAP command <C>PolynomialCoefficientsPolynomial</C>.
