Changes from previous:
----------------------
VERSION 3.20  (2011−12−01)
   NEW CODE(s)

   Added limited support for deprecated codes
       The code2XXX, XXX2code, all_XXX_codes, and all_XXX_names functions
       now support retired codes.  RT 71124

   Pod tests off by default
       The pod tests will not run at install time.  RT 71122

   Codesets may be specified by name
       All codesets may be specified by a constant or by their name now.
           Previously, they were specified only by a constant.

   alias_code deprecated
       The alias_code function exists for backward compatibility.  It has

       been replaced by rename_country_code .  The alias_code function
       will be removed sometime after September, 2013 .

   Code cleanup
       All work is now done in the central module (Locale::Codes).
       Previously, some was still done in the wrapper modules
       (Locale::Codes::*) but that is gone now.

   Added LangFam module
       Added Language Family codes (langfam) as defined in ISO 639−5.

VERSION 3.18  (2011−08−31)
   NEW CODE(s)

   No longer use CIA data
       The CIA world added non‐standard values, so I no longer use it as a
       source of data.  Based on a report by Michiel Beijen.

VERSION 3.17  (2011−06−28)
   NEW CODE(s)

   Added new types of codes

       functions.  RT 69100

   Reorganized code
       Reorganized modules to move Locale::MODULE to Locale::Codes::MODULE
       to allow for cleaner future additions.  The original four modules
       (Locale::Language, Locale::Currency, Locale::Country,
       Locale::Script) will continue to work, but all new sets of codes
       will be added in the Locale::Codes namespace.
