The traditional \lstinline!\overbrace! and \lstinline!\underbrace! pairs have a \mbox{1:1} share between the left and right side (either side of the tip/cust of the brace). Using a \mbox{1:2} ratio would place the brace cusp one third (from the left) into the brace. Similary a \mbox{3:2} ratio would place the cusp 40\% (or two fifths) from the right edge of the brace. + +Other, more complex construction -- by means of the optional \prm{spec} argument -- can also be made by mixing the elements presented in Table~\ref{tab:abrace-spec}. + +\cmditem{newbracespec}{char}{spec} + +This allows the user to define a new brace specification \prm{char} the results in the (possibly complex) construction \prm{spec}.
