NAME
       "LaTeXML::MathParser" - parses mathematics content

DESCRIPTION
       "LaTeXML::MathParser" parses the	mathematical content of	a document.
       It uses Parse::RecDescent and a grammar "MathGrammar".

   Math	Representation
       Needs description.

   Possibile Customizations
       Needs description.

   Convenience functions
       The following functions are exported for	convenience in writing the
       grammar productions.

       "$node =	New($name,$content,%attributes);"
	   Creates a new "XMTok" node with given $name (a string or undef),
	   and $content	(a string or undef) (but at least one of name or
	   content should be provided),	and attributes.

       "$node =	Arg($node,$n);"
	   Returns the $n-th argument of an "XMApp" node; 0 is the operator
	   node.

       "Annotate($node,%attributes);"
	   Add attributes to $node.

       "$node =	Apply($op,@args);"
	   Create a new	"XMApp"	node representing the application of the node
	   $op to the nodes @args.

       "$node =	ApplyDelimited($op,@stuff);"
	   Create a new	"XMApp"	node representing the application of the node
	   $op to the arguments	found in @stuff.  @stuff are delimited
	   arguments in	the sense that the leading and trailing	nodes should
	   represent open and close delimiters and the arguments are separated
	   by punctuation nodes.

       "$node =	InterpretDelimited($op,@stuff);"
	   Similar to "ApplyDelimited",	this interprets	sequence of delimited,
	   punctuated items as being the application of	$op to those items.

       "$node =	recApply(@ops,$arg);"
	   Given a sequence of operators and an	argument, forms	the nested
	   application "op(op(...(arg)))">.

       "$node =	InvisibleTimes;"
	   Creates an invisible	times operator.

       "$boole = isMatchingClose($open,$close);"
	   Checks whether $open	and $close form	a `normal' pair	of delimiters,
	   or if either	is ".".

       "$node =	Fence(@stuff);"
	   Given a delimited sequence of nodes,	starting and ending with
	   open/close delimiters, and with intermediate	nodes separated	by
	   punctuation or such,	attempt	to guess what type of thing is
	   represented such as a set, absolute value, interval,	and so on.

	   This	would be a good	candidate for customization!

       "$node =	NewFormulae(@stuff);"
	   Given a set of formulas, construct a	"Formulae" application,	if
	   there are more than one, else just return the first.

       "$node =	NewList(@stuff);"
	   Given a set of expressions, construct a "list" application, if
	   there are more than one, else just return the first.

       "$node =	LeftRec($arg1,@more);"
	   Given an expr followed by repeated (op expr), compose the left
	   recursive tree.  For	example	"a + b + c - d"	would give "(- (+ a b
	   c) d)">

       "MaybeFunction($token);"
	   Note	the possible use of $token as a	function, which	may cause
	   incorrect parsing.  This is used to generate	warning	messages.
