+%   Here we check if a control sequence named
+%   \cs[no-index]{@pkg-disable@\meta{name}.sty} is defined, and if so
+%   don't use the package loading code |#2|, but use the replacement
+%   code stored in that control sequence, write something to the log,
+%   and then prevent \cs{@onefilewithoptions} from sanity-checking the
+%   requested package date (the \tn{expandafter} here triggers one in
+%   \cs{@onefilewithoptions} that ends a conditional there, and the
+%   \tn{@gobbletwo} removes the date checking code from the input
+%   stream).
