 ## References 
 Although fortran-lang is _not_ interface-compatible with any of the following libraries, each contains documentation that might be useful for different reasons:
+
 * **Recommended reference:** The [scipy.fftpack] documentation contains succinct description of the storage sequences for function results that match those in fortran-lang/fftpack, e.g., the location of the real and imaginary parts of the `rfft` function result.
 * **Theory reference:** The [documentation for the GNU/gsl FFT routines], which are also based on netlib/fftpack, provides some useful definitions of FFT terminology and represenations of the analytical forms of the Discrete Fourier Transform nicely formatted by [LaTeX].
 * **Historical reference:** The [netlib/fftpack] library on which fortran-lang/fftpack is useful for understanding several fortran-lang/fftpack design choices, e.g., the procedure dependencies.
