        !            50: .Nm Fsplit
        !            51: takes as input either a file or standard input containing Fortran source code.
        !            52: It attempts to split the input into separate routine files of the
        !            53: form
        !            54: .Ar name.f ,
        !            55: where
        !            56: .Ar name
        !            57: is the name of the program unit (e.g. function, subroutine, block data or
        !            58: program).  The name for unnamed block data subprograms has the form
        !            59: .Ar blkdtaNNN.f
        !            60: where NNN is three digits and a file of this name does not already exist.
        !            61: For unnamed main programs the name has the form
        !            62: .Ar mainNNN.f .
        !            63: If there is an error in classifying a program unit, or if
        !            64: .Ar name.f
        !            65: already exists,
        !            66: the program unit will be put in a file of the form
        !            67: .Ar zzzNNN.f
        !            68: where
        !            69: .Ar zzzNNN.f
        !            70: does not already exist.

        !            74: Normally each subprogram unit is split into a separate file.  When the
        !            75: .Fl e
        !            76: option is used, only the specified subprogram units are split into separate
        !            77: files.  E.g.:
        !            78: .Pp
        !            79: .Dl fsplit -e readit -e doit prog.f
        !            80: .Pp
        !            81: will split readit and doit into separate files.
        !            82: .El
        !            83: .Sh DIAGNOSTICS
        !            84: If names specified via the
        !            85: .Fl e
        !            86: option are not found, a diagnostic is written to
        !            87: standard error.
