The following sample code from the tikz manual fails with the following
error:

! Package pgfkeys Error: I do not know the key '/pgf/decoration/brace'
and I am
going to ignore it. Perhaps you misspelled it.

See the pgfkeys package documentation for explanation.
Type H <return> for immediate help.
...

l.11 \draw[decorate,decoration=brace]
(a) -- (b);

What am I missing here?

\documentclass{article}
\usepackage{tikz}
\usetikzlibrary{decorations}
\begin{document}

\begin{tikzpicture}
\node (a) {A};
\node (b) at (2,1) {B};
\draw (a) -- (b);
\draw[decorate,decoration=brace] (a) -- (b);
\draw[decorate,decoration={brace,mirror},red] (a) -- (b);
\draw[decorate,decoration={brace,mirror,raise=5pt},blue] (a) -- (b);
\end{tikzpicture}

\end{document}

Thanks, Alain. This is one frustrating part about the otherwise stellar
tikz manual: it's not always obvious which libraries must be used for
which bits of sample code.

First, you can use all the librairies :

\usetikzlibrary{%
arrows,%
calc,%
fit,%
patterns,%
plotmarks,%
shapes.geometric,%
shapes.misc,%
shapes.symbols,%
shapes.arrows,%
shapes.callouts,%
% shapes.multipart,%
% shapes.gates.logic.US,%
% shapes.gates.logic.IEC,%
% er,%
% automata,%
backgrounds,%
chains,%
topaths,%
trees,%
petri,%
mindmap,%
matrix,%
% calendar,%
folding,%
fadings,%
through,%
positioning,%
scopes,%
decorations.fractals,%
decorations.shapes,%
decorations.text,%
decorations.pathmorphing,%
decorations.pathreplacing,%
decorations.footprints,%
decorations.markings,%
shadows}

and after you remove some of them

Best Regards
