%description
Parton-level Monte Carlo program MCFM. The program is designed to calculate 
cross-sections for various femtobarn-level processes at hadron-hadron 
colliders. For most processes, matrix elements are included at 
next-to-leading order and incorporate full spin correlations. For 
more details, including a list of available processes, view the documentation (PDF).
