Current fftw source

+FFTW is a free collection of fast C routines for computing the
+Discrete Fourier Transform in one or more dimensions.  It includes
+complex, real, symmetric, and parallel transforms, and can handle
+arbitrary array sizes efficiently.  FFTW is typically faster than
+other publically-available FFT implementations, and is even
+competitive with vendor-tuned libraries.  (See our web page
+http://fftw.org/ for extensive benchmarks.)  To achieve this
+performance, FFTW uses novel code-generation and runtime
+self-optimization techniques (along with many other tricks).
+
+The doc/ directory contains the manual in texinfo, PDF, info, and HTML
+formats.  Frequently asked questions and answers can be found in the
+doc/FAQ/ directory in ASCII and HTML.
+
+For a quick introduction to calling FFTW, see the "Tutorial" section
+of the manual.
+
+INSTALLATION
+------------
+
+INSTALLATION FROM AN OFFICIAL RELEASE:
+
+Please read chapter 10 "Installation and Customization" of the manual.
+In short:
+
+     ./configure
+     make
+     make install
+
+INSTALLATION FROM THE GIT REPOSITORY:
+
+First, install these programs:
+
+  ocaml, ocamlbuild, autoconf, automake, indent, and libtool,
+
+Then, execute
+
+    sh bootstrap.sh
+    make
+    
+The bootstrap.sh script runs configure directly, but if you need to
+re-run configure, you must pass the --enable-maintainer-mode flag:
+
+    ./configure --enable-maintainer-mode [OTHER CONFIGURE FLAGS]
+
+CONTACTS
+--------
+
+FFTW was written by Matteo Frigo and Steven G. Johnson.  You can
+contact them at [e-mail].  The latest version of FFTW,
+benchmarks, links, and other information can be found at the FFTW home
+page (http://www.fftw.org).  You can also sign up to the fftw-announce
+Google group to receive (infrequent) updates and information about new
+releases.
