+# 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.
+
+See <https://wiki.documentfoundation.org/Development/ReleaseBuilds> for how
+TDF builds make use of these switches.  (Especially, since `--with-package-format`
+now triggers whether or not installation sets are built, all the relevant `*.conf`
+files specify it, except for `LibreOfficeLinux.conf`, where the TDF build
+instructions pass an explicit `--with-package-format="rpm deb"` in addition to
+`--with-distro=LibreOfficeLinux`.)
+
+(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 without any
+parameters at all.
