+%   Here this macro is called \cs{@onefilewithoptions}, but further
+%   ahead in this file it is renamed to \cs{load@onefilewithoptions},
+%   and \cs{@onefilewithoptions} becomes a wrapper around this, used for
+%   bookkeeping when rolling back.  Therefore, when in
+%   \pkg{latexrelease}, we need to define \cs{load@onefilewithoptions}
+%   instead, thus the extra guarded \cs{def} line below:
+%    \begin{macrocode}
