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.
