-!> Perform multiple fast fourier transforms.
-!!
-!! This subprogram performs multiple fast fourier transforms
-!! between complex amplitudes in fourier space and real values
-!! in cyclic physical space.
-!!
-!! Subprograms called (NCEPLIB SP Library):
-!!  - scrft Complex to real fourier transform
-!!  - dcrft Complex to real fourier transform
-!!  - srcft Real to complex fourier transform
-!!  - drcft Real to complex fourier transform
-!!
-!! Program history log:
-!! 1998-12-18  Mark Iredell
-!!
-!! @param[in] imax Integer number of values in the cyclic physical
-!! space. See limitations on imax in remarks below.
-!! @param[in] incw Integer first dimension of the complex amplitude array.
-!! (incw >= imax/2+1).
-!! @param[in] incg Integer first dimension of the real value array.
-!! (incg >= imax).
-!! @param[in] kmax Integer number of transforms to perform.
-!! @param[in] w Complex amplitudes on input if idir>0, and on output
-!! if idir<0.
-!! @param[in] g Real values on input if idir<0, and on output if idir>0.
-!! @param[in] idir Integer direction flag. idir>0 to transform from
-!! fourier to physical space. idir<0 to transform from physical to
-!! fourier space.
-!!
-!! @note The restrictions on imax are that it must be a multiple
-!! of 1 to 25 factors of two, up to 2 factors of three,
-!! and up to 1 factor of five, seven and eleven.
