There are some experimental options. These have not yet been heavily tested and should be used with caution.
@vtable @code
@item	-optg
		globally optimise code generation (full vector)
@item	-make-sort
	use sorted equations (sese, generated by make)
@item	-no-reduce
	try not to use symbolic algebra
@item	-sort
		use sorted equations (sese, generated by seqn)

@subsubsection Deprecated options
C code generation is now deprecated in favour of C++ generation
@vtable @code
@item	-c
		c-code generation

@subsection Model specific options
@cindex Model-specific options
It is often desirable to keep the options used to build a model associated with the directory in which the model is contained, along with information about compiler options or paths to component libraries. In these cases, it is convenient to create an executable shell script, say @code{call_mtt} which sets environment variables and options before calling mtt proper, for example:
@example
@verbatim
#! /bin/sh
# call_mtt: sets model specific environment and options
