{cmd:mlopts} {hline 2} Parsing tool for ml commands

	[{it:rest}]
	[{cmd:,} {it:options} ]


{title:Description}

{pstd}
{cmd:mlopts} is a parsing tool that was written to assist in syntax checking
and parsing of estimation commands that use {cmd:ml}.  The options specified
in {it:options} will be separated into groups and returned in local macros
specified by the caller.  The names of the local macros are identified by
{it:mlopts} and {it:rest}.

{phang}
{it:mlopts} is required and will contain those options that the {cmd:ml}
command recognizes as {it:maximize} options.  Options returned in {it:mlopts}
are:

{pmore}
	{opt tr:ace}
	{opt grad:ient}
	{opt hess:ian}
	{cmd:showstep}
	{opt tech:nique(algorithm_specs)}
	{cmd:vce(}{cmd:oim}|{cmd:opg}{cmd:)}
	{opt iter:ate(#)}
	{opt tol:erance(#)}
	{opt ltol:erance(#)}
	{opt gtol:erance(#)}
	{opt nrtol:erance(#)}
	{opt nonrtol:erance}
	{opt shownrt:olerance}
	{cmdab:dif:ficult}
	{opt const:raints(clist|matname)}

{pmore}
For a description of the above options (except {cmd:constraints()}) see
{help maximize}.  For a description of constraints see {helpb cnsreg} and
{helpb reg3}.

{phang}
{it:rest} is optional and, if specified, will contain all other options that
were not returned in {it:mlopts}.  If {it:rest} is not specified, then any
extra options will cause an error.
