Between version 0.1 and 0.2:

24/1/95:
	Changed default file-directory lookup mechanism to use the
	Tcl command "glob" rather than spawning an "ls".  This is
	much faster, and means the delays are because of the slow
	tree redrawing rather than looking for files.

24/1/95:
	Changed documentation for -command, which now reflects that
	the command is called when the set of selected nodes
	changes by means of mouse actions (and key actions too, should
	I ever add them).  Also, the current selection is appended to
	the command when it is executed.

24/1/95:
	Multiple node-path arguments to "setselection", "addtoselection",
	"removefromselection" and "toggleselection" are now
	allowed.  Also, with -commonselect true, the arguments can be
	single node names instead of node paths.
