**Make arbitrarily structured, arbitrary-dimension boxes and log-normal mocks.**

``powerbox`` is a pure-python code for creating density grids (or boxes) that have an arbitrary two-point distribution
(i.e. power spectrum). Primary motivations for creating the code were the simple creation of log-normal mock galaxy
distributions, but the methodology can be used for other applications.

Features
--------
* Works in any number of dimensions.
* Really simple.
* Arbitrary isotropic power-spectra.
* Create Gaussian or Log-Normal fields
* Create discrete samples following the field, assuming it describes an over-density.
* Measure power spectra of output fields to ensure consistency.
* Seamlessly uses pyFFTW if available for ~double the speed.

Installation
------------
``powerbox`` only depends on ``numpy >= 1.6.2``, which will be installed automatically if ``powerbox`` is installed
using ``pip`` (see below). Furthermore, it has the optional dependency of ``pyfftw``, which if installed will offer
~2x performance increase in large fourier transforms. This will be seamlessly used if installed.

To install ``pyfftw``, simply do::

    pip install pyfftw

To install ``powerbox``, do::

    pip install powerbox

Alternatively, the bleeding-edge version from git can be installed with::

    pip install git+git://github.com/steven-murray/powerbox.git

Finally, for a development installation, download the source code and then run (in the top-level directory)::

    pip install -e .
