cfortran.h

    A transparent, machine independent interface
   between C and Fortran routines and global data,
   developed by Burkhard Burow at CERN.  It provides macros
   which allow the C preprocessor to translate a simple
   description of a C (Fortran) routine or global data into a
   Fortran (C) interface.

   Version 2.6 runs on VAX/VMS/Ultrix, DECstation,
   Silicon Graphics, IBM RS/6000, Sun, Cray, Apollo,
   HP9000, LynxOS, f2c, NAG f90.

   user's experiences with cfortran.h are described in the Jan 93
