Within option code commands

These two commands can be used only within the code argument of either || or ||. Other commands commonly used within these arguments can be found in the next few subsections.

$\begin{decl} \vert\CurrentOption\vert \end{decl}$
This expands to the name of the current option.

$\begin{decl} \vert\OptionNotUsed\vert \end{decl}$
This causes the current option to be added to the list of `unused options'.
