Generalized log-sine functions appear in higher order epsilon-expansion of
different Feynman diagrams. We present an algorithm for numerical evaluation of
these functions of real argument. This algorithm is implemented as C++ library
with arbitrary-precision arithmetics for integer 0 < k < 9 and j > 1. Some new
relations and representations for the generalized log-sine functions are given.
