Fpr the time being, `javax.tools.JavaCompiler.run` may be our best option, although we'll certainly get to the point where we want to leverage the more advanced features of the compiler API.

The options are by and large the same.  Some of the exceptions are 
options like -help, -version, which don't make so much sense on the 
API.  -J will never be accepted by the API because it affects the 
underlying JVM.

Set the PLATFORM_CLASS_PATH, using JavaFileManager.setLocation for the 
file manager you use for the compilation.
