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'.
