> cd procwork

where proc is the process code, e.g. proc =wjet, wqq, Njet, vbjet, etc

The ALPGEN executable for this process is created by the command

> make gen

or

> make gen90

depending on whether you want the F77 or F90 version. The F90 version is quite faster. This executable allows to calculate cross sections, defined by the set of parameters (e.g. the number of jets or the heavy quark masses) and of kinematical cuts (e.g. the minimum pt and rapidity of jets) selected by the user at run time (they can be input interactively) or through an input card file (using e.g. the template provided by the file input)
