###                        Read a LaTeX file, or an .aux file, and
###                        extract the citation tags, outputting them
###                        one per line on stdout, in sorted order.
###
###                        The companion program, citefind, can be
###                        used to extract the complete BibTeX entries
###                        for those tags from a bibliography file.
###                        This is useful when a small bibtex file
###                        must be prepared from large citation
###                        databases.
###
###                        Usage:
###                             citetags latex-file--or--aux-file >newbibfile

###                        The checksum field above contains a CRC-16
###                        checksum as the first value, followed by the
###                        equivalent of the standard UNIX wc (word
###                        count) utility output of lines, words, and
###                        characters.  This is produced by Robert
###                        Solovay's checksum utility.",
