"""
Helper script to update sampleproject's translation catalogs.
When a bug has been identified related to i18n, this helps capture the issue
by using catalogs created from management commands.
Example:
The string "Two %% Three %%%" renders differently using translate and
blocktranslate. This issue is difficult to debug, it could be a problem with
extraction, interpolation, or both.
How this script helps:
* Add {% translate "Two %% Three %%%" %} and blocktranslate equivalent to templates.
* Run this script.
* Test extraction - verify the new msgid in sampleproject's django.po.
* Add a translation to sampleproject's django.po.
* Run this script.
* Test interpolation - verify templatetag rendering, test each in a template
that is rendered using an activated language from sampleproject's locale.
* Tests should fail, issue captured.
* Fix issue.
* Run this script.
* Tests all pass.
