Dear all,

I'm looking for a way to solve a simple optimization problem with a 
nonlinear constraint. An example would be

max x   s.t.       y = x * T ^(x-1)

where y and T are known values.

optim() and constrOptim() do only allow for box or linear constraints, 
so I did not succedd here. I also found hints to donlp2 but this does 
not seem to be available anymore.

Any hints are welcome,
