Pre-canned distribution configurations These files are supposed to correspond to the options used when creating the Document Foundation (or other "canonical") builds of LibreOffice for various platforms. They are *not* supposed to represent the "most useful" options for developers in general. On the contrary, the intent is that just running ./autogen.sh without any options at all should produce a buildable configuration for developers with interest in working on the most commonly used parts of the code. (Possibly the above is a misunderstanding, or maybe there never even has been any clear consensus what situations these files actually are intended for.) The files contain sets of configuration parameters, and can be passed on the autogen.sh command line thus: ./autogen.sh --with-distro=LibreOfficeFoo Contrary to the above, in the Android case the amount of parameters you just must use is so large, that for convenience it is always easiest to use the corresponding distro-configs file. This is a bug and needs to be fixed; also configuring for Android should ideally use sane (or the only possible) defaults and work fine wihout any parameters at all.
