+Building
+--------
+
+Libnet employs the GNU configure and build system.  The release tarballs
+ship with a pre-built `configure` script.  To list available options,
+type <kbd>./configure --help</kbd>
+
+When checking out the code from GitHub, use <kbd>./autogen.sh</kbd> to
+generate a `configure` script.  For this you need the full suite of the
+GNU autotools: autoconf (>=2.69), automake (>=1.14), libtool (>=2.4.2).
+On Debian/Ubuntu systems:
+
+    sudo apt install autoconf automake libtool

+    sudo apt install doxygen pod2man
+
+For neat graphics in the HTML documentation, also install graphviz.
+There is also a PDF version of the docs, to build that you need quite a
+few more packages:
+
+    sudo apt install texlive-extra-utils texlive-latex-extra \
+                     texlive-fonts-recommended latex-xcolor  \
+                     texlive-font-utils
+
+Fior Microsoft CHM docs you need the HTML Help Workshop, which is part
+of Visual Studio: http://go.microsoft.com/fwlink/p/?linkid=154968, on
+UNIX and GNU/Linux systems, see `chmcmd`, which is available in the
+[FreePascal](http://www.freepascal.org/) suite:
+
+    sudo apt install fp-utils-3.0.4
