Pre-canned distribution / platform configurations When the software is configured for a platform, since we run on so many platforms, detecting the best sequence of configure options to get it building is hard. Instead we have a text file containing the recommended (often the distributed) version of these parameters, one per distribution or significant platform. These are interpreted by autogen.sh and eventually end up passed to configure. Thus: ./autogen.sh --with-distro=LibreOfficeAndroid might build a version tweaked for Android.
