+occurrence of another (specified) token list.  The package's mechanism differs
+from those of packages providing similar features, in the following ways: the
+method uses TeX's mechanism of reading delimited macro parameters; splitting
+macros work by pure expansion, without assignments; the operation is carried
+out in a single macro call.  A variant of the operation is provided, that
+retains outer braces.")
