## Revision 1.9  2009/11/02 16:54:03  geraint
## Replaced deprecated functions from Octave 2.1 for Octave 3.0: is_struct -> isstruct, struct_contains -> isfield, struct_elements -> fieldnames, is_complex -> iscomplex, setstr -> char
##
## Revision 1.8  2001/06/13 16:07:15  gawthrop
## Fixed bug with three separators in a row eg )/(
##
## Revision 1.7  2001/06/13 14:50:15  gawthrop
## Operator ^ now ok in args in abg and/or lbl
##
## Revision 1.6  2001/04/23 16:23:30  gawthrop
## Now stips ; from bottlom level argument list - allows aliasing of
## parts of a,b,c (eg a,b by using a,b;c
##
## Revision 1.5  2000/10/12 19:27:20  peterg
## Now writes out the aliased args ...
##
## Revision 1.4  2000/09/14 13:35:43  peterg
## appended '(' and ')' to SEPS
##   -- otherwise first argument after '(' doesn't get substituted
## (Fixed by Geraint)
##
## Revision 1.3  1998/08/11 14:09:05  peterg
## Replaced incorrect length(args>0) with !isempty(args)
##
## Revision 1.2  1998/07/27 10:24:20  peterg
## Included , in the the list of seperators (SEPS)
## This makes it substitute for bits of args separated by commas.
