Often, when building an application, I've had occasions where I need to provide
a nonce of some sort to a user. A nonce is some thing, whether number, or
otherwise, that is used only once.
The over-arching goal was for this to be simple to use,
and reasonably fast. Next, I wanted something that the average user would be
able to enter manually with minimal risk. This ruled out a lot of the crazy
mixed-case alphanumeric strings that are often used. Finally,
a goal was to have a reasonably large number of permutations available so
that the nonce, while not cryptographically strong, was strong enough for
uses like registration, password reset, etc. For example, with the default
`word source`_, and a selection of three words, there are
`almost 19 billion permutations`_ available. Presuming you're doing any form
of brute-force-attack prevention, this should be more than adequate.

The list of words comes from the `New General Service List`_ v1.01. The original
list, distributed in Excel format, is covered under the
`Creative Commons Attribution 3.0 Unported License`_. More information can be
found on the website. From the base data, the following changes have been made:
#. The list was converted from Excel to a simple one-word-per-line text file
2. Only headwords were retained for clarity;
3. Supplemental words, such as months and numbers, were added;
3. Words less than 4 characters were removed.
Combined, a total of 2,668 headwords were retained.

The library is trivially easy to use::
>>> from generalwords import *
('climb', 'repair', 'force')
In the future, there may be more options, but not right now.
Not Done Yet
While the library will never be massively complicated, there's a few things I'd
like to have in the future:
* Expand to other languages
* Add additional word sources
* First release on PyPI.
