+/* These Fourier routines were originally based on the Fourier
+routines of the same names from the NETLIB bihar and fftpack
+fortran libraries developed by Paul N. Swarztrauber at the National
+Center for Atmospheric Research in Boulder, CO USA.  They have been
+reimplemented in C and optimized in a few ways for OggSquish. */
+
+/* As the original fortran libraries are public domain, the C Fourier
+routines in this file are hereby released to the public domain as
+well.  The C routines here produce output exactly equivalent to the
+original fortran routines.  Of particular interest are the facts
+that (like the original fortran), these routines can work on
+arbitrary length vectors that need not be powers of two in
+length. */
