+# Install several packages at once
+If you want to install from source different packages, using `catkin_make_isolated` without re-compiling existing packages (that are downloaded since they're dependencies) you can follow this:
+Prepare you workspace
+    mkdir my_wksp
+    cd my_wksp
+Generate the packages list
+    rosinstall_generator stack1 packageb blabla --rosdistro hydro --wet-only --deps --exclude RPP > all.rosinstall
+Download the packages, update the workspace
+    wstool init -j8 src all.rosinstall
+    # or, if you're working with an existing workspace
+    # wstool merge all.rosinstall -t src
+    # wstool update -j8 -t src
+Install system dependencies
+    rosdep install --from-paths src --ignore-src --rosdistro hydro -y -r
+    # Add "--os=debian:wheezy" if you need (not needed on ubuntu, might be needed on debian)
+Compile
+    catkin_make_isolated -q --merge --install-space /opt/ros/hydro/
+Install !
+    sudo /opt/ros/hydro/env.sh catkin_make_isolated --install --install-space /opt/ros/hydro/ -q --merge
+That should be it. If you compare to the other examples (Debian install, Turtlebot install), you might notice some changes:
+* `--exclude RPP` is used to exclude the already installed packages from the dependencies search
+* Two lines for catkin_make_isolated instead of one: That's because compiling as root is bad
