                     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.
