+<h4 class="subsection">4.7.4 Wisdom Utilities</h4>
+
+<p>FFTW includes two standalone utility programs that deal with wisdom.  We
+merely summarize them here, since they come with their own <code>man</code>
+pages for Unix and GNU systems (with HTML versions on our web site).
+</p>
+<p>The first program is <code>fftw-wisdom</code> (or <code>fftwf-wisdom</code> in
+single precision, etcetera), which can be used to create a wisdom file
+containing plans for any of the transform sizes and types supported by
+FFTW.  It is preferable to create wisdom directly from your executable
+(see <a href="Caveats-in-Using-Wisdom.html#Caveats-in-Using-Wisdom">Caveats in Using Wisdom</a>), but this program is useful for
+creating global wisdom files for <code>fftw_import_system_wisdom</code>.
+<a name="index-fftw_002dwisdom-utility-1"></a>
+</p>
+
+<p>The second program is <code>fftw-wisdom-to-conf</code>, which takes a wisdom
+file as input and produces a <em>configuration routine</em> as output.  The
+latter is a C subroutine that you can compile and link into your
+program, replacing a routine of the same name in the FFTW library, that
+determines which parts of FFTW are callable by your program.
+<code>fftw-wisdom-to-conf</code> produces a configuration routine that links
+to only those parts of FFTW needed by the saved plans in the wisdom,
+greatly reducing the size of statically linked executables (which should
+only attempt to create plans corresponding to those in the wisdom,
+however).
