Classification: 11.1.

External routines: GNU Scientific Library (GSL); the Les Houches Accord pdf Interface (LHAPDF).

Nature of problem:
Computation of the total cross-section in perturbative QCD.

Solution method:
Numerical integration of the product of hard partonic cross-section (with or without soft gluon resummation) with two parton distribution functions.

Additional comments:
Sub per-mill accuracy achievable in realistic time (program does not employ Monte Carlo methods).

Running time:
Depending on the options. The program is optimized for speed.
