NAME
	plot_xyz

SUMMARY
	Name	plot_xyz
	Type	data
	Inputs	none
	Output	geom
	Parameters	Name		Type		Default
			Filename	string		NULL
			Close Region	boolean		true

DESCRIPTION

	This module reads an ASCII file consisting of lists of
	x,y,z points and constructs a polyline geometry object
	using the points in the file as vertices.

	The file format this module expects is as follows:

	num_vertices		(integer)
	x y z			(floating point values)
	x y z
	  .
	  .
	x y z
	num_vertices		(integer)
	x y z
	x y z
	  .
	  .
	x y z
	<eof>


PARAMETERS

	Filename
		A file browser is supplied allowing the user to specify
		a filename for plot_xyz to read.

	Close Region
		A boolean flag which, if true, indicates that a line 
		segment will inserted between the first and last vertices.
		The value of this flag is applied to each set of vertices
		in the file.

OUTPUTS

	A GEOMedit_list which contains a polyline connecting the vertices
	of each group of vertices specified by the user.
