CLASS DESCRIPTION    [Toc]    [Back]

	  The VkForkIO class provides an easy mechanism	to run a shell command
	  in a text widget, and	allow the user to interact with	that command
	  as if	they were in a shell.  The VkForkWindow	class further
	  simplifies this by allowing a	command	to be run in a new window.

FUNCTION DESCRIPTIONS    [Toc]    [Back]

   VkForkIO()
	   VkForkIO(const char*	name,
		    Widget parent,
		    const char*	prompt = NULL);
	   virtual void	~VkForkIO(void);


	  Creates a Motif scrolled text	widget for command interaction.	 The
	  first	argument is the	name used for the text widget, the second is
	  used for the parent of the text widget, and the last is the
	  command-line prompt displayed.

   execCommand()
	   void	execCommand(char* cmd);
