  The classical Kronecker limit formula gives the constant term of the
non-holomorphic Eisenstein series E(z,s) for SL(2,Z) at s=1 in terms of the
Dedekind eta function. Here we compute the analagous formula for an Eisenstein
series twisted by modular symbols (periods of weight two holomorphic cusp
forms) for general Fuchsian groups of the first kind.
