# Herwig++(1)

Multi-purpose Monte-Carlo event generator for particle physics.

## NAME

Herwig++ - Multi-purpose Monte-Carlo event generator for particle physics.

## SYNOPSIS

**Herwig++** *(read\|run)* \[*OPTIONS*\]... \[*FILE*\]

## DESCRIPTION

Herwig++ is a multi-purpose Monte-Carlo event generator for particle physics. See arXiv:0803.0883 for a detailed manual, or arXiv:1101.2599 for a more general description of the physics behind MC event generation.

One of the commands 'read' or 'run' is required:

-

  read - reads an input file and creates a run file,

-

  run  - reads a run file and generates events.

- **-h**, **--help**

  Print help and exit

- **--full-help**

  Print help, including hidden options, and exit

- **-V**, **--version**

  Print version and exit

Event generation options:

- **-N**, **--numevents**=*LONG*

  Number of events to generate.

- **-s**, **--seed**=*INT*

  The random number generator seed.

- **-t**, **--tag**=*TAG*

  A tag to append to the run name.  (default=\`')

- **-d**, **--debug**=*INT*

  Set the ThePEG debug level.

- **-D**, **--debug-fpe**

  Enable floating point exceptions.  (default=off)

- **-q**, **--quiet**

  Disable event counter.  (default=off)

Plugin library options:

- **-l**, **--append**=*PATH*

  Append a search path for dynamically loaded libraries.

- **-L**, **--prepend**=*PATH*

  Prepend a search path for dynamically loaded libraries.
