+\begin{describe}{sym}{int}
+  The symbol @|int| is exported by the @|sod-utilities| package, without
+  giving it any particular meaning.  This is done because it's given
+  non-conflicting meanings by two different packages, and it's more
+  convenient for user code not to have to deal with an unnecessary symbol
+  conflict.  Specifically, the @|sod| package wants to define it as a C type
+  specifier, see \descref{cls}{simple-c-type}; and @|optparse| wants to
+  define it as an option handler, see \descref{opt}{int}.
