xamarin/XobotOS

* Our updated version of Sharpen, see below for changes.

* Fully translated Java to C# code, classes that have been
  translated in this way contain the attribute [Sharpen.Sharpened]

* Empty C# stubs based on the Java declaration: these are
      needed as intermediate steps to get things to build in the
      new C# world.  Classes with empty stubs are decorated with
      the [Sharpen.NakedStub] attribute

android/extra-sources:

* Custom written code that either fine tunes the port,
      provides an alternative optimized version to a class or
      provides a runtime facility.

android/api:

* XML files that describe the translation process from Java to C#.

android/upstream:

* Google's Android 4.0 source code.

libxobotos:

* Glue code to integrate with various Android C++ libraries as
      well as the Linux X11 host that sets up the toplevel window
      and the optional OpenGL context.

* Mostly calls into Skia, Jpeg, OpenGL and ICU libraries.

binaries:

* Libraries to get you started without requiring you to build Skia,
  and other native Android tools.

* Screenshots, videos, and some basic precompiled samples.

monodevelop:

    * Add-in to build native XobotOS applications with MonoDevelop

samples:

* Ported samples to C# using XobotOS

external:

* Native libraries needed to build the unmanaged libxobotos C library

* Java generics

* XML-driven translation process

* Type remapping for native Java types to C# types, and supports
  for custom type mappings.

* Support for translating code that does native interop

* Support for generating C's .c and .h files for native glue
      (to assist in P/Invoke support)

* Add attribute-supported translations

* Improved incremental compilation
