 How to use Herwig++  (Parton level analysis)
==================================================

STEP1: 
If you change model files, do
       $ Herwig++ init 

STEP2: 
To make .run file, do
       $ Herwig++ read filename.in

STEP3: 
To make events, do
       $ Herwig++ run filename.run -N1000
Then you can make 1000 events.

STEP4:
Edit analysis_hoge.cpp. You can define variables, cuts and so on in this file.

STEP5:
Do	$ make
	$ ./analysis_hoge hpp.root test.top
	$ td -d ps test.top
Then you find graphs in test.ps.


------------------------------
	filename.in
------------------------------

Choose events you want to make.

You can change particle mass as follows.

set /Herwig/Particles/h0:NominalMass 150.*GeV
set /Herwig/Particles/t:NominalMass 200.*GeV
set /Herwig/Particles/tbar:NominalMass 200.*GeV


You should specify the filename.run as follows.

###############################################
# Save run for later usage with 'Herwig++ run'
###############################################
saverun filename LHCGenerator

NOTICE: When you copy the filename.in to make newfilename.in,
you should not forget changing above line. Otherwise your
filename.run is overwritten.
