  SpartyJet is a set of software tools for jet finding and analysis, built
around the FastJet library of jet algorithms. SpartyJet provides four key
extensions to FastJet: a simple Python interface to most FastJet features, a
powerful framework for building up modular analyses, extensive input file
handling capabilities, and a graphical browser for viewing analysis output and
creating new on-the-fly analyses. Many of these capabilities rely on a
ROOT-based backend. Beyond finding jets, many jet tools in SpartyJet perform
measurement of jet or event variables, available to subsequent tools and stored
in the final output. SpartyJet can be downloaded from HepForge at
http://projects.hepforge.org/spartyjet.
