"""

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.
