def Merge.mergeProcess	(	*	inputFiles,

_mergeProcess_

Creates and returns a merge process that will merge the provided
filenames

supported options:

- process_name : name of the process, defaults to Merge
- outputmod_label : label of the output module, defaults to Merged
- newDQMIO : specifies if the new DQM format should be used to merge the files
- output_file : sets the output file name
- output_lfn : sets the output LFN
- mergeNANO : to merge NanoAOD
- bypassVersionCheck : to bypass version check in case merging happened in lower version of CMSSW (i.e. UL HLT case). This will be FALSE by default.
