"""
This config fragment generates LHE information for tau embedding. The selection step must be carried out beforehand.
It's normally used together with the cleaning step.
With `--procModifiers` one can specify wheather to simulate/embed muons (`tau_embedding_mu_to_mu`) or electrons (`tau_embedding_mu_to_e`) instead of taus.
To use this config fragment, a cmsDriver command like the following can be used:
```
cmsDriver.py \
	--step USER:TauAnalysis/MCEmbeddingTools/LHE_USER_cff.embeddingLHEProducerTask,RAW2DIGI,RECO \
	--processName LHEembeddingCLEAN \
	--data \
	--scenario pp \
	--eventcontent TauEmbeddingCleaning \
	--datatier RAWRECO \
	--procModifiers tau_embedding_cleaning,tau_embedding_mu_to_mu \
    --era ... \
    --conditions ... \
    --filein ... \
    --fileout ...
```
