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