+     "The LaTeX package @code{gobble} includes several gobble macros not
+included in the LaTeX kernel.  These macros remove a number of arguments after
+them, a feature regulary used inside other macros.  This includes gobble
+macros for optional arguments.
+
+The LaTeX package @code{gobble-user} provides these macros at the user level,
+i.e.  using names without @samp{@@@@} so that these can be used without
+@code{\\makeatletter} and @code{\\makeatother}.  The same macros are provided
+inside @file{.tex} files for use with plain-TeX or other TeX formats.
+However, the gobble macros for optional macros require @code{\\@@@@ifnextchar}
+to be defined.")
