I don't know how strict we are trying to be with [PEP-257](http://www.python.org/dev/peps/pep-0257/) (docstring conventions), but:

> The docstring is a phrase ending in a period. It prescribes the function or method's effect as a command ("Do this", "Return that"), not as a description; e.g. don't write "Returns the pathname ...".

So the convention prescribes:

`Perform unsupervised Wiener-Hunt deconvolution.`
