Fantastic! Thanks for the perseverance :)

The default is 10 events: use e.g. "-n 1000" (or "-n 1k", due to me
showing off!) to change that to 1000 events. Other parameters are set
with "-p NAME=VALUE" or with "-P PARAMFILE". The param files are picked
up from a variety of include paths as well as the current directory, so
e.g. "-P fpythia-atlas-ambt1.params" will find the parameters for the
new ATLAS AMBT1 PYTHIA tune from the $prefix/share/AGILe/params directory.

I hope you manage to get PHOJET to work. Please let us know if you have
technical questions about how the AGILe interfaces work... I can
certainly help out with the more techie bits.
