Module:Lang relies upon a series of Lua data modules that are transcribed from the IANA language-subtag-registry file:

All of these modules can be updated by using Module:Language/data/iana_languages/make and copy/pasting the appropriate sections of that module's output into the related data module. This is a crude awb script that can be used to update all of the data modules in a more 'automatic' manner. The script fetches the language-subtag-registry file from the IANA website and then parses it apart and updates the various modules.

The process is:

  1. open awb and load the settings file.
  2. click start
  3. review the changes, and if acceptable, click save; repeat 'til done.
