NAME

       bibzbladd.pl - add Zbl numbers to papers in a given bib file

SYNOPSIS

       bibzbladd  [-d] [-f] [-e 1|0] [-o output] bib_file

OPTIONS

       -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.

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

DESCRIPTION

       The script reads a BibTeX file.  It checks whether the entries have Zbls.  If not, tries
       to contact internet to get the numbers.  The result is a BibTeX file with the fields
       "zblnumber=..." 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.
