Fingerprint -- Document Fingerprint Generator

---------------------------------------------

Fingerprint is a signature of the document. In particular, it is a representative subset of hash values from the set of all hash values of a document. For more detail, please consider taking a look at [Winnowing: Local Algorithms for Document Fingerprinting](http://theory.stanford.edu/~aiken/publications/papers/sigmod03.pdf) *(specifically Figure 2)*.

Fingerprint Module Installation

-------------------------------

The recommended way to install the `fingerprint` module is to simply use `pip`:

```console

$ pip install fingerprint

```

Fingerprint officially supports Python >= 3.0.

How to use fingerprint?

-----------------------

```pycon

>>> import fingerprint

>>> fprint = fingerprint.Fingerprint(kgram_len=4, window_len=5, base=10, modulo=1000)

>>> fprint.generate(str="adorunrunrunadorunrun")

>>> fprint.generate(fpath="../CHANGES.txt")

```

The default values for the parameters are

```python

kgram_len = 50

window_len = 100

base = 101

modulo = sys.maxint

```
