    	The routines in this directory are from netlib/bihar.
    	Although, they look like they are derivitaves of the following
    	package.

    	The Fortran files have been translated to the C-language with
    	f2c, which is also available from netlib.

    	Note: Actually the version of fftpack on netlib is slightly
    	different. This version is a double-precision version. If you
    	want to compile it with a Fortran compiler (the original
    	source), either use IMPLICIT statements, or get the Fortran
    	source from: netlib/bihar

    	The command used to generate the C source was `f2c *.f'

    	To make:

    	1) Type `./configure'

    	The options configure will recognize:

    	--with-prefix=install_prefix_pathname

    	--with-cc=full_cc_pathname
    	--with-ld=full_ld_pathname
    	--with-ar=full_ar_pathname
    	--with-ranlib=full_ranlib_pathname

    	These options are designed to allow users to specify alternate
    	programs to use so that cross compiling can be performed. If
    	you are compiling this library for a native platform then you
    	should not need to specify any options.

    	2.) Type `make'

    	3.) Type `make -n install'

    	The default installation directory is `/usr/local/lib'. If you
    	wish to install the library in another directory the do:

    		make -n install prefix=/usr/wherever/lib

    	3a) If you are satisfied with the "make install" command
    	output, then retype the command without the `-n'.
