+/*! \page page_fft FFT Signal Processing Blocks
+
+\section Introduction
+
+This is the gr-scigen package. It contains signal processing blocks to
+perform FFTs and FFT-related functionality.
+
+The Python namespace is in gnuradio.fft, which would be normally
+imported as:
+
+\code
+ from gnuradio import scigen
+\endcode
+
+See the Doxygen documentation for details about the blocks available
+in this package. A quick listing of the details can be found in Python
+after importing by using:
+
+\code
+ help(scigen)
+\endcode
+
+\section Dependencies
+
+The scigen blocks require the following dependencies.
+
+\li fftw3f (>= 3.0) http://www.fftw.org/download.html
