/// The D0 code has been obtained from Lars Sonnenschein's web-space
/// http://www-d0.fnal.gov/~sonne/D0RunIcone.tgz

/// The version of the D0 Run I code distributed
/// here has been modified by the FastJet authors, so as to provide
/// access to the contents of the jets (as is necessary for the
/// plugin). This does not modify the results of the clustering.
///
/// The difference between this algorithm and the post-1996 version
/// relates to the way the final jet momenta are calculated. Details
/// are to be found in FERMILAB-PUB-97-242-E.
