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.
the text file with the zone information. Use "-" for standard input.
the output database filename
show version information, and quit (don't do anything)
Use "Oz" area zone. Default is 1. (What does this mean, exactly?)
"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.
