-## @deftypefn {} {} usage (@var{msg})
-##
-## @code{usage} is deprecated and will be removed in Octave version 4.4.
-## Please use @code{print_usage} in all new code.
-##
-## Print the message @var{msg}, prefixed by the string @samp{usage: }, and
-## set Octave's internal error state such that control will return to the
-## top level without evaluating any more commands.  This is useful for
-## aborting from functions.
-##
-## After @code{usage} is evaluated, Octave will print a traceback of all
-## the function calls leading to the usage message.
-##
-## You should use this function for reporting problems errors that result
-## from an improper call to a function, such as calling a function with an
-## incorrect number of arguments, or with arguments of the wrong type.  For
-## example, most functions distributed with Octave begin with code like
-## this
-##
-## @example
-## @group
-## if (nargin != 2)
-##   usage (\"foo (a, b)\");
-## endif
-## @end group
-## @end example
-##
-## @noindent
-## to check for the proper number of arguments.
-## @seealso{print_usage}
-## @end deftypefn
-
-## Deprecated in version 4.0
