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.
OPTIONS
-r zonefile
the text file with the zone information.
Use "-" for standard input.
-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, exactly?)
-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.
