-  --create duplicates.csv # create new project from file
-  --info "duplicates" # show project metadata
-  --apply duplicates-deletion.json "duplicates" # apply rules in file to project
-  --export "duplicates" # export project to terminal in tsv format
-  --export --output=deduped.xls "duplicates" # export project to file in xls format
-  --delete "duplicates" # delete project
-
-Some more examples:
-  --info 1234567890123 # specify project by id
-  --create example.tsv --encoding=UTF-8
-  --create example.xml --recordPath=collection --recordPath=record
