+### N-Triples Comments and White Space
+
+Non-canonical RDF N-Triples files may contain optional comments at the end of each data line.
+`kgtk import-ntriples` will strip any comments it encounters. It also strips any non-canonical
+white space (multiple adjacent white space characters).

+Example comment:
