82 <p>As explained in <a href="Words-of-Wisdom_002dSaving-Plans.html#Words-of-Wisdom_002dSaving-Plans">Words of Wisdom-Saving Plans</a>, FFTW provides a
83 &ldquo;wisdom&rdquo; API for saving plans to disk so that they can be recreated
84 quickly. The C API for exporting (see <a href="Wisdom-Export.html#Wisdom-Export">Wisdom Export</a>) and
85 importing (see <a href="Wisdom-Import.html#Wisdom-Import">Wisdom Import</a>) wisdom is somewhat tricky to use
86 from Fortran, however, because of differences in file I/O and string
87 types between C and Fortran.
