       The script reads a BibTeX file.  It checks whether the entries have Zbls.  If not, it tries to  find  the
       numbers from Internet sites. The result is a BibTeX file with "zblnumber=..." fields added.

       The  name  of the output file is either set by the -o option or is derived by adding the suffix "_zbl" to
       the output file.

       See the "bibdoiadd" script for more details on the processing.

-d  Debug mode

       -e  If 1 (default), add an empty zblnumber if a zbl cannot be found.  This prevents repeated searches for
           the same entries if you add new entries to the file.  Calling "-e 0" suppresses this behavior.

       -f  Force searching for Zbl numbers even if the entry already has one.

       -ooutput
           Output  file.  If this option is not used, the name for the output file is formed by adding "_zbl" to
           the input file
