Most of this was obsolete and misleading

ios/README

 experimental iOS apps that use LibreOffice code.
-
-experimental/LibreOffice - Uses the "normal" desktop-style main loop
-and output mechanism to display the document, and also accepts input
-and selections. Broken since the tiled rendering changes. As tiled
-rendering seems to be what will/should be used, this app is of limited
-usefulness now. (Don't get excited by the name of this app, it was
-never intended to become a "complete" LibreOffice in any sense. In
-retrospect it was silly to call it just "LibreOffice.)
-
-Note that this app is built using gbuild: The executable as a normal
-executable from gbuild's perspective, and the app bundle then using a
-CustomTarget that constructs it. Its Xcode project has no normal
-"Compile Sources" or "Link Binary" build phases but instead a "Run
-Script" one that runs make.
-
-experimental/TiledLibreOffice - Uses tiled rendering and CATiledLayer.
-No input handling, but scrolling around and zooming around works
-nicely. Displays the number of tiles rendered per second. Also the
-name of this app is a bit too grandiose. Built by an Xcode project.
-(When built from the shell, running xcodebuild).
-
-MobileLibreOffice - Uses the code in "shared" subdirectory. Can be
-built in two configurations: 1) the "normal" configurations (Debug and
-Release) that matches experimental/LibreOffice in functionality, more
-or less. (But the coded is entirely differently structured.) But also
-this is currently broken, 2) the Debug_tile_tester configuration,
-where one can tweak tiling parameters and see a tile rendered. Also
-built by an Xcode project.
