@@ -69,3 +69,44 @@ compare it to your \code{configure.ac}. What are the differences?
 
 Run \code{make dist}, and look at the tarball that is generated. Your
 project is ready to be released!
+
+Now, run \code{git add} on \code{configure.ac}, \code{Makefile.am} and
+\code{hello.c}, and do a new commit: \code{git commit -s -m ``Add a
+  real program''}. If you run \code{git status}, you can see that
+there are really a lot of files generated by {\em autotols}, so add a
+\code{.gitignore} file to tell Git to simply ignore them. This file
+should contain something like:
+
+\begin{verbatim}
+.deps/
+Makefile
+Makefile.in
+aclocal.m4
+autom4te.cache/
+compile
+config.log
+config.status
+configure
+depcomp
+hello
+hello.o
+install-sh
+missing
+\end{verbatim}
+
+The files \code{configure.scan} and \code{autoscan.log} can simply be
+removed, they would only get re-created if we run \code{autoscan}
+again.
+
+Commit your \code{.gitignore} file
+
+\begin{verbatim}
+git add .gitignore
+git commit -s -m ``Add gitignore file''
+\end{verbatim}
+
+Now at any time you can do \code{git clean -xdf} to ask Git to remove
+all the files that are not under version control. This allows to
+easily get rid of all the files generated by the {\em autotools} and
+see more clearly what's part of your project.
