Synopsis

       Parses BibTeX files.

           use BibTeX::Parser;
               use IO::File;

           my $fh = IO::File->new("filename");

           # Create parser object ...
           my $parser = BibTeX::Parser->new($fh);

           # ... and iterate over entries
           while (my $entry = $parser->next ) {
                   if ($entry->parse_ok) {
                           my $type    = $entry->type;
                           my $title   = $entry->field("title");

                           my @authors = $entry->author;
                           # or:
                           my @editors = $entry->editor;

                           foreach my $author (@authors) {
                                   print $author->first . " "
                                       . $author->von . " "
                                       . $author->last . ", "
                                       . $author->jr;
                           }
                   } else {
                           warn "Error parsing file: " . $entry->error;
                   }
           }
