Before starting my work on the CLDR I was overly optimistic.
Just a few lua scripts with a json or xml library seemed
enough. But after my initial efforts it was clear a lot of
thing had to done by hand. Currently I write ad hoc Python
scripts (batteries included, you know) for specific tasks
(for example, I few days ago I added ‘likely’ bcp47 tags
to many ini files).
