"""Generate events and write to file or stdout
EXAMPLES:
%prog <gen> [-p<param> ...] [-P<pfile> ...] \\
[-n<nevts>] [-o<outfile>] [--sqrts=<energy>] \\
[--beams=<beamsstr>] \\
[--seed=<rngseed> | --randomize-seed]
%prog --list-gens
%prog --list-used-params
BEAM SPEC:
Beams can be specified in several different schemes. The
strings are compared case-insensitively. Energies are
specified in GeV. The energy must be explicitly specified,
either as part of the beam string (after a colon) or via
the --sqrts option.
* --beams=p:900,pbar:900
* --beams=ppbar:1960
* --beams=LHC:14000
* --beams=pp:14T
Beam particles:
* "proton", "2212", "p", "p+"
* "antiproton", "-2212", "pbar", "p-"
* "electron", "11", "e-"
* "positron", "-11", "e+"
Beam pair strings:
* pp: "LHC", "PP", "RHIC"
* ppbar: "TEVATRON", "TVT", "PPBAR"
* e+e-: "LEP", "E+E-", "EE"
ENVIRONMENT:
* AGILE_GEN_PATH
Colon-separated list of filesystem paths which get checked
in order when searching for generator libraries in the
Genser structure. The current directory and the AGILe install
path are also searched, after AGILE_GEN_PATH.
* AGILE_PARAM_PATH
Colon-separated list of filesystem paths which get checked
in order when searching for generator parameter files as
passed to the -P option. The current directory and the AGILe
install path are also searched, after AGILE_PARAM_PATH.
* AGILE_DEBUG
Enables debug output level if set
