HELP	On-line documentation. 
 	HELP, by itself, lists all primary help topics.  Each primary topic
 	corresponds to a directory name on MATLABPATH.
 
 	"HELP topic" gives help on the specified topic.  The topic can be
 	a command name or a directory name.  If it is a command name, HELP
 	displays information on that command.  If it is a directory name, 
 	HELP displays the Table-Of-Contents for the specified directory.
 	It is not necessary to give the full pathname of the directory; 
 	the last component, or last several components, are sufficient.
 
 	For example, "help general" and "help matlab/general" both list
 	the Table-Of-Contents for the directory toolbox/matlab/general.
 
 	LOOKFOR XYZ looks for the string XYZ in the first comment line
 	of the HELP text in all M-files found on MATLABPATH.  For all files
 	in which a match occurs, LOOKFOR displays the matching lines.
 
 	MORE ON causes HELP to pause between screenfuls if the help text
 	runs to several screens.
