"""Loads translations from CSV files in a directory.
Translations are strings with optional Python-style named placeholders
(e.g., ``My name is %(name)s``) and their associated translations.
The directory should have translation files of the form ``LOCALE.csv``,
e.g. ``es_GT.csv``. The CSV files should have two or three columns: string,
translation, and an optional plural indicator. Plural indicators should
be one of "plural" or "singular". A given string can have both singular
and plural forms. For example ``%(name)s liked this`` may have a
different verb conjugation depending on whether %(name)s is one
name or a list of names. There should be two rows in the CSV file for
that string, one with plural indicator "singular", and one "plural".
For strings with no verbs that would change on translation, simply
use "unknown" or the empty string (or don't include the column at all).
The file is read using the `csv` module in the default "excel" dialect.
In this format there should not be spaces after the commas.
Example translation ``es_LA.csv``::
"I love you","Te amo"
"%(name)s liked this","A %(name)s les gustó esto","plural"
"%(name)s liked this","A %(name)s le gustó esto","singular"
