1.3       aaron      50: .Nm fsplit
1.1       deraadt    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.

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

1.3       aaron      96: .Nm fsplit
1.1       deraadt    97: assumes the subprogram name is on the first noncomment line of the subprogram
                     98: unit.  Nonstandard source formats may confuse
                     99: .Nm fsplit .
                    100: .Pp
                    101: It is hard to use
                    102: .Fl e
                    103: for unnamed main programs and block data subprograms since you must
                    104: predict the created file name.
