'''
Spelling
========

Provides abstracted access to a range of spellchecking backends as well as
word suggestions. The API is inspired by enchant but other backends can be
added that implement the same API.

Spelling currently requires `python-enchant` for all platforms except
OSX, where a native implementation exists.
