framer is a tool to generate boilerplate code for C extension types.
The boilerplate is generated from a specification object written in
Python. The specification uses the class statement to describe the
extension module and any extension types it contains. From the
specification, framer can generate all the boilerplate C code,
including function definitions, argument handling code, and type
objects.

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>

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.
