Hello, There are examples (usually one paragraph long) in my lecture text, and I want them to be typeset in smaller font (\tfx). An excerpt: The entities in question fall into two broad categories: {\em endogenous} (intrinsic to the SUI itself) and {\em exogenous} (belonging to a system's environment). \example{All processes that take place inside Earth (and other planets) are considered endogenous. These processes make the continents migrate, push the mountains up, trigger earthquakes and volcanism, and are driven by the warmth that is produced in the core of Earth.} More text... I hesitate about how to define \example. I know about \definedescription and \defineenumeration, but they seem not much logically suitable to me. What could you advise? Regards, Vyatcheslav
