\section{Tags}
\begin{itemize}
\item Output Tags

	This set of tags control how and when data gets sent to the
	student, it also provides hints to the data's markup and when
	it should be autoconverted, and when it should be ignored. All
	of these tags except \tag{outtext} are valid and parsed by  
	\&parsed() inside a \tag{script}.

	Additionaly any perl style variables are replaced with the values
	of the variable in the problem namespace.

	\begin{itemize}

	\item \tag{outtext} all data inside is assumed to be valid
	html, the handler will attempt to autoconvert to the output
	type. The only thing tags allowed inside are the ones listed
	below.

	\item \tag{target} This tag specifies data that is not in HTMl
	format inside an \tag{outtext}. Takes a required argument
	\arg{type} and an optional argument \arg{dest}. \arg{type}
	specifies a known valid output target which is the format of
	the data. \arg{dest} specifies a list of possible output
	targets that the data should be autoconverted for. The
	\arg{type} of the data is assumed to be a \arg{dest}. If the
	current target is not a \arg{dest} then the data is ignored.

	\item \tag{tex} shorthand for $<$target type=``tex''$>$
	\arg{dest} is a valid argument.

	\item \tag{ascii} shorthand for $<$target type=``ascii''$>$
	\arg{dest} is a valid argument.

	\item \tag{web} shorthand for $<$target type=``web''$>$
	\arg{dest} is a valid argument.

	\item \tag{mathml} shorthand for $<$target type=``mathml''$>$
	\arg{dest} is a valid argument, mathml may be passed along
	unconverted in a web output target.

	\end{itemize}
\item Form Elements:

	This set of tags soley generate a representation of the proper
	form element on the output device. Need to look at what should
	be provided when an exam is wanted.

	\begin{itemize}
	\item \tag{radio} 
	
	web - provides a single button to check on and off, when checked on
	all other radio buttons in the current \tag{answergroup} level
	will be set to off.
	
	tex - generates a circle before the data inside

	\item \tag{list}
	
	web - provides a drop down box of all the possible options

	tex - the list is displayed an students can select the correct option

	\item \tag{textline}
	
	web - a single line of reponse is provided to type into.

	tex - a line is provided.

	\item \tag{textarea}

	web - a textarea form is provided allowing multiples lines of response

 	tex - a configureable number of lines is provided, configured through 
	      the argument numlines, defaults to 10

	\item \tag{check}
	
	web - either a checkbutton, or two radio buttons are provided

	tex - a small box that can be checked is provided.

	\item \tag{button} -  Not sure this is useful

	\end{itemize}
\item Randomiztion
	\begin{itemize}
	\item \tag{randomlist} this tag will cause the parser to randomly select the order that it parses the next level of tags, tags another leveldown will be done in order though.Example
\tag{randomlist}\\
\hspace5pt \tag{tag1}\\
		\tag{subtag1}\\
		\tag{/subtag1}\\
		\tag{subtag2}\\
		\tag{/subtag2}\\
	\tag{/tag1}\\
	\tag{tag2}\\
		\tag{subtag1}\\
		\tag{/subtag1}\\
		\tag{subtag2}\\
		\tag{/subtag2}\\
	\tag{/tag2}\\
\tag{/randomlist}\\
In this example, \tag{tag1} or \tag{tag2} will be done first, but \tag{subtag1} will always happen before \tag{subtag2}.
