The RooUnfold package provides a common framework to evaluate and usedifferent unfolding algorithms, side-by-side. It currently provides implemen-tations or interfaces for the Iterative Bayes, SVD, and TUnfold methods, aswell as bin-by-bin and matrix inversion reference methods. Common toolsprovide covariance matrix evaluation and multi-dimensional unfolding. A testsuite allows comparisons of the performance of the algorithms under differ-ent truth and measurement models. Here I outline the package, the unfoldingmethods, and some experience of their use.
