       mkzonedb - Utility create a zone file for isdnlog


       mkzonedb -r zonefile -d database [-v] [-V] [-o Oz] [-l len]


       mkzonedb  reads  a  text  file  with  zone (area code) information, and
       writes it in a special format to the database file so that  other  apps
       such as isdnlog can easily access the data.

       This  data  is used to determine in what "zone" a given area code is in
       relation to another, to see what rate applies to a call  between  these
       area codes ("is the call a local call").

       This  utility  is  really only used during the building of the isdnlog-
       data package, but it may be useful for those who want to  create  their
       own custom tables.


       -r zonefile
              the  text  file with the zone information.  Use "-" for standard

       -d database
              the output database filename

       -v     verbose mode

       -V     show version information, and quit (don’t do anything)

       -o Oz  Use "Oz"  area  zone.  Default  is  1.  (What  does  this  mean,

       -l len "len" is the length of areacodes.
              If  5  or  more  is  given, then more space is allocated for the
              internal tables (40000 instead of 10000 numbers allowed).  Other
              values aren’t really used.
