NAME

     fsplit -- split a multi-routine Fortran file into individual files

SYNOPSIS

     fsplit [-e efile] ...  [file]

DESCRIPTION

     fsplit takes as input either a file or standard input containing Fortran source code.  It attempts to split the input into separate routine
     files of the form name.f, where name is the name of the program unit (e.g. function, subroutine, block data or program).  The name for
     unnamed block data subprograms has the form blkdtaNNN.f where NNN is three digits and a file of this name does not already exist.	For
     unnamed main programs the name has the form mainNNN.f.  If there is an error in classifying a program unit, or if name.f already exists, the
     program unit will be put in a file of the form zzzNNN.f where zzzNNN.f does not already exist.

     -e efile	 Normally each subprogram unit is split into a separate file.  When the -e option is used, only the specified subprogram units are
		 split into separate files.  E.g.:

		       fsplit -e readit -e doit prog.f

		 will split readit and doit into separate files.

DIAGNOSTICS

     If names specified via the -e option are not found, a diagnostic is written to standard error.

HISTORY

     The fsplit command appeared in 4.2BSD.

BUGS

     fsplit assumes the subprogram name is on the first noncomment line of the subprogram unit.  Nonstandard source formats may confuse fsplit.

     It is hard to use -e for unnamed main programs and block data subprograms since you must predict the created file name.
