**polib** allows you to manipulate, create, modify gettext files (pot, po
and mo files). You can load existing files, iterate through it's entries,
add, modify entries, comments or metadata, etc... or create new po files
from scratch.
**polib** provides a simple and pythonic API, exporting only three
convenience functions (*pofile*, *mofile* and *detect_encoding*), and the
four core classes, *POFile*, *MOFile*, *POEntry* and *MOEntry* for creating
new files/entries.
**Basic example**:
>>> import polib
>>> # load an existing po file
>>> po = polib.pofile('tests/test_utf8.po')
>>> for entry in po:
... # do something with entry...
... pass
>>> # add an entry
>>> entry = polib.POEntry(msgid='Welcome', msgstr='Bienvenue')
>>> entry.occurrences = [('welcome.py', '12'), ('anotherfile.py', '34')]
>>> po.append(entry)
>>> # to save our modified po file:
>>> # po.save()
>>> # or you may want to compile the po file
>>> # po.save_as_mofile('tests/test_utf8.mo')
