Libfft Version 2.3 is very similar to Version 2.2,
the only changes made fix a minor bug with SFFT2DU and DFFT2DU.

The current library comes in four formats:

o mips1: compilation flags -O2, 
	will run on all systems,
	can be link with C or Fortran compilers. 
	This is NOT a parallel version.

o mips2: compiled with the "-O2 -mips2" flags,
	will run only on systems with R4000 CPUs, 
	can be used with both C and Fortran compilers.
	This is NOT a parallel version.

o mp_mips1: compiled "-O2 -mp" 
	will run all systems. 
	Requires Fortran compilers since it uses the Fortran MP library.
	This version will run in parallel on Power Series systems.

o mp_mips2: compiled "-O2 -mips2 -mp" (ELF format)
	will run all Challenge and Onyx systems only. 
	Requires Fortran compilers since it uses the Fortran MP library.
	This version will run in parallel.

Note the "mp_mips2" versions was compiled under Irix5.0 and the corresponding
compilers. The object files use the new ELF format, while the other three
versons of the library use the classical COFF format.

The TRY directory contain test and timing drivers. 

Finally in the DOC directory you will find a ASCII documentation file.
