Dear Maintainer,

The Debian package page for libsleef says
"SLEEF also includes subroutines for discrete Fourier transform(DFT)."
and sleef.org/dft.xhtml says

#include "sleef.h"
#include "sleefdft.h"
...
$ gcc tutorial.c -lsleefdft -lsleef ... -lm

but sleefdft.h is not to be found under /usr/include
nor libsleefdft.* under /usr/lib
