a) If using source code from the repository (not a tarball download),
   you must bootstrap the source tree:

     autoreconf --install

   This must be done:
   - after checking out the code for the first time
   - after changing configure.ac or any Makefile.am file

   NOTE: the bootstrap process only works reliably when using the same
         (or a very similar) version of autotools as the officially
         tested reSIProcate releases.  The official releases are
         bootstrapped using autotools on a Debian 6.0 (squeeze) system.

b) Run configure:

   e.g. on a Debian system:

     ./configure --with-ssl --with-mysql --with-c-ares \
               CXXFLAGS="-DRESIP_FIXED_POINT"

   NOTE: some things (e.g. reTurnServer) will ONLY build if you
         specify --with-ssl to link against SSL libraries

   A more complete example, with tfm:

     ./configure \
       --with-ssl --with-mysql --with-radius --with-tfm \
       --enable-ipv6 \
       CXXFLAGS="-I`pwd`/contrib/Netxx-0.3.2/include" \
       LDFLAGS="-L`pwd`/contrib/Netxx-0.3.2/src"

     (hint: if it fails to link against libNetxx.so, create a symlink, or
            delete libNetxx.so and it should link against libNetxx.a)

     OR (using contrib/ares)

     ./configure --with-ssl --with-mysql --enable-ipv6 --with-popt"

c) Build everything:

     make

   or to build just one thing:

     make -C rutil

   and if you have multiple CPUs/CPU-cores/hyper-threading, you can build
   faster by telling make to use them in parallel, e.g.:

     make -j 12

d) Test it, e.g. to test rutil:

     make -C rutil check

e) Install somewhere:

     mkdir /tmp/my-resip && make DESTDIR=/tmp/my-resip install
