\section{Python "hook" activation}
\begin{frame}[fragile]{Python ``hook'' activation}
	\begin{itemize}
		\item{Some projects already offer Python extensions
                  (pretty printers, type printers, etc.) to be run
                  when \gdb{} loads them (e.g., \texttt{libstdc++}).}

		\item{The distro needs to arrange things for \gdb{} to
                  lookup those files in the right directories.  Fedora
                  uses \texttt{/usr/share/gdb/auto-load}.}

		\item{You have to provide
                  \verb|--with-auto-load-dir| and
                  \verb|--with-auto-load-safe-path| to the
                  \texttt{configure} script when compiling.}

		\item{Inside the auto-load directory, the files need
                  to be named after their ``parent'' libraries.  For
                  example, for the \texttt{libstc++} hook file, the
                  full path is (on Fedora)
                  \texttt{/usr/share/gdb/auto-load/usr/lib64/libstdc++.so.6.0.17-gdb.py}}
