NAME
       Graph::Flowchart::Node - A node in a Graph::Flowchart, representing a
       block/expression

SYNOPSIS
	       use Devel::Graph;

	       my $graph = Devel::Graph->graph( ’$a = 9 if $b == 1’ );

	       print $graph->as_ascii();

DESCRIPTION
       This module is used by Devel::Graph internally, there should be no
       need to use it directly.

       EXPORT

       Exports nothing on default but can export on request the following:

	 N_START N_END N_BLOCK N_IF N_THEN N_ELSE N_JOINT N_END N_FOR N_BODY
	 N_SUB
	 N_CONTINUE N_GOTO N_RETURN N_BREAK N_NEXT N_LAST
	 N_USE

METHODS
       new()

	       my $node = Graph::Flowchart::Node->new( $text, $type, $label);
	       my $node = Graph::Flowchart::Node->new( $text, $type);

       Create a new node of the given $type with the $text as label. The
       optional $label is the label for "goto".

       For instance:

	       LABEL: $a = 1;
	       goto LABEL;

       would be turned into:

	       my $n1 = Graph::Flowchart::Node->new( "$a = 1;\n", N_BLOCK, ’LABEL’);
	       my $n2 = Graph::Flowchart::Node->new( "goto LABEL;\n", N_GOTO);
