Usage: bibtex_munge [-hR] filename

The filename should be the name of a .bib or .bcf file. If it is a .bib file, the output
will consist of cleaned and normalized bibliography entries. If it is a .bcf file,
in addition to cleaning and sanitizing, a subset bibliography will be created: only those
entries that were actually cited in the document from which the .bcf was created will
be retained.

Options:
  --help -h     show this message
  --replace -R  rather than printing the output to STDOUT, save it as filename.bib, and
                move the former contents of filename.bib to filename.bib.bak
