###################################################################
#
# This is the main repository setup file for Herwig++.
#
# It is read using the 'Herwig++ init' command.
#
# The 'Herwig++ read' step allows additional configuration
# instructions to be read from a run-specific file, to modify the
# default values. (We provide LEP.in, ILC.in, LHC.in and TVT.in as
# examples)
#
# You will not need to change any settings here.
# Any modifications can be made in your own input files.
#
###################################################################
###################################################################
# The repository contains its own internal directory structure to
# keep track of created objects. (This is entirely independent of
# the file system)
###################################################################
# Make all the directories in the Repository we need
mkdir /Defaults
mkdir /Defaults/Matchers
mkdir /Defaults/Particles

###################################################################
# The 'read' command includes external files in place, to reduce
# clutter. You can also use it for blocks of settings you're likely
# to use again and again.

# The 'create' command creates an object in the repository from
# a C++ class. The arguments are (1) the C++ class name, (2) your
# chosen repository name, and optionally, (3) the library name where
# the class can be found.
#
# Created objects are _not_ automatically associated to a run. They
# need to be assigned to it using a chain of 'set' or 'insert'
# commands (see below).

# The EventHandler is the most important object in a run. It
# (directly or indirectly) owns most of the objects that have been
# created up to now.
#
# Below we create one handler for LEP and one for LHC.
#
# Try to understand the following few lines (also look at the external
# .in files if you can't find the 'create' line for an object).
#
# If you need to make modifications, it's best to make them in your
# own input file (for the 'Herwig++ read' step) and not here.

# Finally, the EventGenerator objects are responsible

# that will be called with the 'run' command to start the event
