+
+<p><a name="index-guru-interface-239"></a>
+The &ldquo;guru&rdquo; interface to FFTW is intended to expose as much as possible
+of the flexibility in the underlying FFTW architecture.  It allows one
+to compute multi-dimensional &ldquo;vectors&rdquo; (loops) of multi-dimensional
+transforms, where each vector/transform dimension has an independent
+size and stride. 
+<a name="index-vector-240"></a>One can also use more general complex-number formats, e.g. separate real
+and imaginary arrays.
+
+   <p>For those users who require the flexibility of the guru interface, it is
+important that they pay special attention to the documentation lest they
+shoot themselves in the foot.
