world -- Print mappings between country names and DNS country codes.

This script will take a list of Internet addresses and print out where in the

world those addresses originate from, based on the top-level domain country

code found in the address.  Addresses can be in any of the following forms:



    xx                -- just the country code or top-level domain identifier

    host.domain.xx    -- any Internet host or network name

    somebody@where.xx -- an Internet email address



If no match is found, the address is interpreted as a regular expression [*]

and a reverse lookup is attempted.  This script will search the country names

and print a list of matching entries.  You can force reverse mappings with the

`-r' flag (see below).



For example:



    %% world tz us

    tz originated from Tanzania, United Republic of

    us originated from United States



    %% world united

    united matches 6 countries:

        ae: United Arab Emirates

        uk: United Kingdom (common practice)

        um: United States Minor Outlying Islands

        us: United States

        tz: Tanzania, United Republic of

        gb: United Kingdom





 [*] Note that regular expressions must conform to Python 1.5's re.py module

 syntax.  The comparison is done with the search() method.



Country codes are maintained by the RIPE Network Coordination Centre,

in coordination with the ISO 3166 Maintenance Agency at DIN Berlin.  The

authoritative source of counry code mappings is:



    <url:ftp://info.ripe.net/iso3166-countrycodes>



The latest known change to this information was:



    Thu Aug  7 17:59:51 MET DST 1997



This script also knows about non-geographic top-level domains.



Usage: world [-d] [-p file] [-o] [-h] addr [addr ...]



    --dump

    -d

        Print mapping of all top-level domains.



    --parse file

    -p file

        Parse an iso3166-countrycodes file extracting the two letter country

        code followed by the country name.  Note that the three letter country

        codes and numbers, which are also provided in the standard format

        file, are ignored.



    --outputdict

    -o

        When used in conjunction with the `-p' option, output is in the form

        of a Python dictionary, and country names are normalized

        w.r.t. capitalization.  This makes it appropriate for cutting and

        pasting back into this file.



    --reverse

    -r

        Force reverse lookup.  In this mode the address can be any Python

        regular expression; this is matched against all country names and a

        list of matching mappings is printed.  In normal mode (e.g. without

        this flag), reverse lookup is performed on addresses if no matching

        country code is found.



    -h

    --help

        Print this message.
