"""
This config fragment contains a customiser function which modifies the process.
In this modification the beamspot and the vertex is adjusted to the measured one.
The simulation GEN step must be carried out beforehand.
To use this config fragment, a cmsDriver command like the following can be used:
```
cmsDriver.py \
	--step HLT:Fake2+TauAnalysis/MCEmbeddingTools/Simulation_HLT_customiser_cff.embeddingHLTCustomiser \
	--processName SIMembeddingHLT \
	--mc \
	--beamspot DBrealistic \
	--geometry DB:Extended \
	--eventcontent TauEmbeddingSimHLT \
	--datatier RAWSIM \
    --era ... \
    --conditions ... \
    --filein ... \
    --fileout ...
```
