## Revision 1.336  2002/05/07 23:50:34  geraint
## Preliminary support for Matlab dynamically linked shared objects:
## invoke with: mtt -cc sys rep mexglx
## ode2odes support is not yet included.
##
## Revision 1.335  2002/05/01 17:30:55  geraint
## Improved pre-processor directives to better accommodate future alternatives (matlab)
## if necessary.
##
## Revision 1.334  2002/05/01 14:10:22  gawthrop
## Added -dr foo (reads from dir foo) option

## Revision 1.31  2002/05/02 20:12:45  geraint
## Added -Wl,--rpath to MTT_CXXLIBS. Sets the runtime linker path so that the

## ode2odes support is not yet included.
##
## Revision 1.46  2002/05/07 13:48:43  geraint
## Improved clarity of code generated for -cc and -oct (except ode2odes).
## Octave DEFUN_DLDs now call (rather than replace) their .cc equivalents.
##
## Revision 1.45  2002/05/02 09:30:22  gawthrop
## _ssim.m now returns t as 4th arg
