world -- Print mappings between country names and DNS country codes. Contact: Barry WarsawEmail:   bwarsaw@python.org This script will take a list of Internet addresses and print out where in theworld those addresses originate from, based on the top-level domain countrycode 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 namesand 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.  Theauthoritative 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. Local Variables:indent-tabs-mode: nilEnd:
