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.

       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.

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.
