+This is a GTK+ Webkit app that is intended to work siilar enough to
+the iOS app that problems in that also show up in this app, and can be
+fixed by people with no Mac or iOS device.
+
+How to build this:
+
+Use a separate tree of "online". Do NOT use one where you build a
+normal Online.
+
+Run autogen.sh, then configure:
+
+./configure --disable-ssl --enable-gtkapp --with-lo-path=/home/tml/lo/cp-6.0/instdir --with-lokit-path=/home/tml/lo/cp-6.0/include
+
+Obviously, adjust the path to your LibreOffice build tree as necessary.
+
+Then make.
+
+You will get the gtk/mobile executable. Run it. Debug it. Fix it.
