'''
For simple use-cases, automatic prescale sets can be generated according to the following rules.
 
To apply them, add the "_{prescale_set}_prescale" prefix to the provided menu name.
E.g. `flags.Trigger.triggerMenuSetup='MC_pp_run3_v1_NoBulkMCProd_prescale'`.
 
This is NOT meant to be used in data-taking, only for development tests and standard reprocessings/MC productions.
 
For any more complex prescale sets, refer to the `TrigMenuRulebook` (used to create PS sets for data-taking), 
located at: https://gitlab.cern.ch/atlas-trigger-menu/TrigMenuRulebook/
