You can escape the @-sign by surrounding it with braces, for example: @. And escape a closing brace within an
inline tag by adding an opening brace in front of it like this: }.

Here are example texts where you can see how they could be used in a real life situation:

    This is a text with an {@internal inline tag where a closing brace (}) is shown}.
    Or an {@internal inline tag with a literal {@link} in it}.

Do note that an {@internal inline tag that has an opening brace ({) does not break out}.
