+IKVM MonoTouch
+==============
+
+This code is based on release 0.46.0.1 of [IKVM] and is modified to allow operation with
+[MonoTouch]. The two big challenges in supporting MonoTouch are:
+
+ * MonoTouch uses AOT compilation to deploy to iOS, and thus cannot support dynamic code
+ generation. IKVM uses dynamic code generation extensively to support fast reflection.
+
+ * MonoTouch only provides the Silverlight runtime profile, which lacks a substantial number of the
+ features of the desktop profile, on which IKVM relies.
+
+These challenges have largely been overcome:
+
+ * Reflection is supported through standard CLR reflection (which is slower than code generation,
+ but at least it works).
+
+ * The Silverlight profile is accommodated by aggressive pruning of the JDK with which IKVM
+ operates. This means that the vast majority of the "enterprisey" features of OpenJDK are not
+ available via IKVM MonoTouch.
+
+Building
+--------
+
+IKVM MonoTouch can (naturally) only be built on a Mac which has MonoTouch installed. You also need
+to install [NAnt](http://nant.sourceforge.net/) (as it's no longer bundled with MonoTouch). Once
+you've installed NAnt, you need to patch your `bin/NAnt.exe.config` file using the
+`NAnt.exe.config.patch` in the top-level directory of ikvm-monotouch.
+
+In addition to this project, you need to check out the [ikvm-openjdk] repository in the same
+directory that contains the `ikvm-monotouch` checkout. The IKVM build will use the Java source in
+the `ikvm-openjdk` directory during its build.
+
+Once you have created your symlink and checked out `ikvm-openjdk`, you can build everything using
+the `build.sh` script:
+
+ ./build.sh
+
+This will generate all of the IKVM dlls and exes in the `ikvm-monotouch/bin` directory. This
+version of IKVM can then be used in the normal manner to convert Java bytecode to a dll that can be
+included in a MonoTouch project.
+
+JNI is supported by including the bin/libikvm-natives.a file in your MonoTouch project. The file
+needs to be copied, not linked, otherwise MonoTouch does not pick it up. You have to add the
+following arguments to IPhone Build -> Additional mtouch arguments:
+
+ -nosymbolstrip -nostrip -cxx -gcc_flags "-L${ProjectDir} -likvm-natives -force_load ${ProjectDir}/libikvm-natives.a"
+
+Your JNI code must use the jni.h file found in native/. Setup an XCode static library project, add
+your JNI files plus a reference to native/jni.h. Then add the static library just like you add the
+libikvm-native.a file (including the mtouch arguments to force link all symbols).
+
+It is not necessary to use this custom project to convert C# dlls to Java stub classes (via
+`ikvmstub.exe`), but you can use it, and save yourself the trouble of installing a standard IKVM
+distribution.
+
+Limitations
+-----------
+
+There are numerous limitations, too many to enumerate. However, this project is successfully
+enabling the [PlayN] game development library to convert Java game projects into iOS binaries.
+
+One known limitation that can probably be overcome is the lack of `java.net` support. The
+aggressive pruning of the OpenJDK to remove all of the enterprise functionality that could not be
+supported on Silverlight resulted in `java.net` being cut out due non-trivial internal dependencies
+on JNDI and from there into a bunch of enterprise crap.
+
+I strongly suspect that the JNDI and other enterprise crap can be surgically removed, leaving a
+functional `java.net` which supports basic DNS and TCP/UDP. However, that will take more time and
+effort than I have thus far been able to muster.
