I'd like to use the PaVeReduce function within FeynCalc in Mathematica
 to reduce a triangle integral down to bubbles and tadpoles. I found
 the wolfram help page about this function but I did not find what
all the options meant with the result that I was unable to produce
 the reduction I wanted.

I have used other software for this reduction and I know what the answer
 is so I'm just playing about with FeynCalc at the moment. I tried

     PaVeReduce[C0[0, m^2, m^2/y, 0, 0, m^2]] // TraditionalForm

but this didn't do the required reduction. I played about with the options too in

     SetOptions[PaVeReduce, A0ToB0 -> True, BReduce -> True, Collecting -> True, Dimension -> True, FCVerbose -> False, Factoring -> Factor2, IsolateNames -> False, Mandelstam -> {}, PaVeAutoReduce -> True, PaVeOrderList -> {}, WriteOutPaVe -> True]

but couldn't get the reduction to go ahead.

Thanks for any comments! There is also the possibility that I am using
the wrong function because I know that Pass-Velt prescription is usually
 done for the reduction of tensor to scalar integrals and I'm trying to do
a scalar to sum of simpler scalar integrals reduction.
