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.
