Important warning

At the end of the ${\logo META}$ ${\logo FONT}$ code we have to place
$\begin{mfcode} end \end{mfcode}$
Semicolon is not required here (but you can use it) because ${\logo META}$ ${\logo FONT}$ ignores everything which might appear after the end token. It is important to place end–of–line character at the last line of code. If you forget it, ${\logo META}$ ${\logo FONT}$ will award you with a horrible message

! METAFONT capacity exceeded, sorry [buffer size=500].

If you really absolutely need more capacity,
you can ask a wizard to enlarge me.
