+\subsection{Feature tests}\label{featuretests}
+
+Some library features may not be always available even if they were selected by
+the user. To make it possible to check if this is the case, the library
+predefines the symbols in the form \texttt{wxHAS\_FEATURE}. Unlike 
+\texttt{wxUSE\_FEATURE} symbols which are defined by the library user (directly
+in \texttt{setup.h} or by running configure script) and which must be always
+defined as either $0$ or $1$, the \texttt{wxHAS} symbols are only defined if
+the corresponding feature is available and not defined at all otherwise.
