        !             2: \f(CWf2c\fP: A Fortran 77 to C Converter
        !             3: .AU
        !             4: S. I. Feldman
        !             5: .AI
        !             6: Bellcore
        !             7: .AU
        !             8: D. M. Gay
        !             9: N. L. Schryer
        !            10: .AI

        !            12: .AU
        !            13: M. W. Maimone
        !            14: .AI
        !            15: Carnegie Mellon University
        !            16: .PP
        !            17: Several Fortran to C converters are commercially available, but
        !            18: none are useful for projects bigger than a few hundred lines;
        !            19: their error rates are measured in percents.
        !            20: For large-scale conversions, error rates near one in a million are needed.
        !            21: Having a reliable Fortran to C converter is of immense interest and value
        !            22: to our research, where we mix Fortran and C in various environments
        !            23: and architectures.
        !            24: .PP
        !            25: We have produced a Fortran 77 (f77) to C converter,
        !            26: with the aid of a summer student, Mark Maimone, from Carnegie-Mellon University.
        !            27: The program is based on the original f77 compiler
        !            28: that was written by S. I. Feldman
        !            29: many years ago and is still in heavy use.
        !            30: .PP
        !            31: That compiler internally constructs a C parse-tree, then produces C
        !            32: intermediate code for the second pass of the C compiler.
        !            33: We produce a C program from the internal C tree.
        !            34: .PP
        !            35: The converter, dubbed \f(CWf2c\fP, has been used internally for some time
        !            36: and is ready for distribution.
        !            37: .PP
        !            38: Feldman's collaboration in this project made it possible \(em
        !            39: there is nothing like having the author of a program advise on its
        !            40: alteration.
        !            41: Since Feldman is at Bellcore and the work was done jointly at AT&T Bell Laboratories and Bellcore,
        !            42: and since we undertook this project with the understanding
        !            43: that its fruits would be made publicly available,
        !            44: we propose putting the resulting f77 to C converter software in the public domain.
        !            45: This will be accomplished by putting the program and its documentation,
        !            46: see the attached "man page,"
        !            47: through a publication release, from both AT&T and Bellcore.
