   6 This script will take a list of Internet addresses and print out where in the
   7 world those addresses originate from, based on the top-level domain country
   8 code found in the address.  Addresses can be in any of the following forms:
   9
  10     xx                -- just the country code or top-level domain identifier
  11     host.domain.xx    -- any Internet host or network name
  12     somebody@where.xx -- an Internet email address
  13
  14 If no match is found, the address is interpreted as a regular expression [*]
  15 and a reverse lookup is attempted.  This script will search the country names
  16 and print a list of matching entries.  You can force reverse mappings with the
  17 `-r' flag (see below).
  18
  19 For example:
  20
  21     %% world tz us
  22     tz originated from Tanzania, United Republic of
  23     us originated from United States
  24
  25     %% world united
  26     united matches 6 countries:
  27         ae: United Arab Emirates
  28         uk: United Kingdom (common practice)
  29         um: United States Minor Outlying Islands
  30         us: United States
  31         tz: Tanzania, United Republic of
  32         gb: United Kingdom
  33
  34
  35  [*] Note that regular expressions must conform to Python 1.5's re.py module
  36  syntax.  The comparison is done with the search() method.
  37
  38 Country codes are maintained by the RIPE Network Coordination Centre,
  39 in coordination with the ISO 3166 Maintenance Agency at DIN Berlin.  The
  40 authoritative source of counry code mappings is:

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

  48 This script also knows about non-geographic top-level domains.
  49
  50 Usage: world [-d] [-p file] [-o] [-h] addr [addr ...]
  51
  52     --dump
  53     -d
  54         Print mapping of all top-level domains.
  55
  56     --parse file
  57     -p file
  58         Parse an iso3166-countrycodes file extracting the two letter country
  59         code followed by the country name.  Note that the three letter country
  60         codes and numbers, which are also provided in the standard format
  61         file, are ignored.
  62
  63     --outputdict
  64     -o
  65         When used in conjunction with the `-p' option, output is in the form
  66         of a Python dictionary, and country names are normalized
  67         w.r.t. capitalization.  This makes it appropriate for cutting and
  68         pasting back into this file.
  69
  70     --reverse
  71     -r
  72         Force reverse lookup.  In this mode the address can be any Python
  73         regular expression; this is matched against all country names and a
  74         list of matching mappings is printed.  In normal mode (e.g. without
  75         this flag), reverse lookup is performed on addresses if no matching
  76         country code is found.
  77
  78     -h
  79     --help
  80         Print this message.
