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 con-
     taining 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 diag-
     nostic is written to standard error.

BUGS
     Fsplit assumes the subprogram name is on the first noncom-
     ment line of the subprogram unit.	Nonstandard source for-
     mats 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.
