+@code{\\MakeRobustCommand} that could be used to make fragile commands robust.
+The LaTeX format has, since 2015, included a command @code{\\MakeRobust} with
+the same syntax and behaviour.  Also by 2019, almost all commands in LaTeX
+that may be used in a moving argument are already robust.  This package is now
+just a simple one-liner defining the name @code{\\MakeRobustCommand} as an
+alias for @code{\\MakeRobust}.  This package should not be used in any new
+documents.")
