        !            35: .Nm Fsplit
        !            36: takes as input either a file or standard input containing Fortran source code.
        !            37: It attempts to split the input into separate routine files of the
        !            38: form
        !            39: .Ar name.f ,
        !            40: where
        !            41: .Ar name
        !            42: is the name of the program unit (e.g. function, subroutine, block data or
        !            43: program).  The name for unnamed block data subprograms has the form
        !            44: .Ar blkdtaNNN.f
        !            45: where NNN is three digits and a file of this name does not already exist.
        !            46: For unnamed main programs the name has the form
        !            47: .Ar mainNNN.f .
        !            48: If there is an error in classifying a program unit, or if
        !            49: .Ar name.f
        !            50: already exists,
        !            51: the program unit will be put in a file of the form
        !            52: .Ar zzzNNN.f
        !            53: where
        !            54: .Ar zzzNNN.f
        !            55: does not already exist.

        !            61: .Cx
        !            62: Normally each subprogram unit is split into a separate file.  When the
        !            63: .Fl e
        !            64: option is used, only the specified subprogram units are split into separate
        !            65: files.  E.g.:
        !            66: .Pp
        !            67: .Dl fsplit -e readit -e doit prog.f
        !            68: .Pp
        !            69: will split readit and doit into separate files.
        !            70: .Tp
        !            71: .Sh DIAGNOSTICS
        !            72: If names specified via the
        !            73: .Fl e
        !            74: option are not found, a diagnostic is written to
        !            75: standard error.
