It should be discoverable \nwith a call to pkg-config::\n\n  $ pkg-config --libs fftw3\n\nLocal or non-system installation locations are supported using \nPKG_CONFIG_PATH::\n\n  $ export PKG_CONFIG_PATH=$HOME/local/lib/pkgconfig\n  $ pkg-config --libs fftw3\n\nUsing pip\n---------\n\nThe recommended way to install the package is via pip::\n\n  $ pip install fftw-cffi\n\nUsing setup.py \n--------------\n\nThis method is suitable for environments where pip is not available, or for \ntesting modifications to the package::\n\n  $ python setup.py install\n\nContributing\n============\n\nGuidelines\n----------\n\nThe development team welcomes feedback, code and enhancement proposals to the \npackage from the community. Please consider opening an issue or submitting \npatches for inclusion to the code base via pull-request. For code \ncontributions, please provide appropriate test cases for each new features and \nverify that the complete test suite runs successfully.\n\nRunning the tests\n-----------------\n\nIf the bindings were modified, then one should first rebuild the CFFI module \nwith::\n\n  $ python setup.py build_ext --inplace\n\nBefore running the test suite with a call to::\n\n  $ python setup.py nosetests\n\nLicense\n=======\n\nThe **fftw-cffi** source code is released under the terms of the `new BSD \nlicense <https://opensource.org/licenses/BSD-3-Clause>`_.
