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.

AUTHORS
     Asa Romberger and Jerry Berkman

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.
