JIT documentation
=================
:abstract:
When a interpreter written in RPython is translated into an executable, the
executable contains a full virtual machine that can optionally
include a Just-In-Time compiler. This JIT compiler is **generated
automatically from the interpreter** that we wrote in RPython.
This JIT Compiler Generator can be applied on interpreters for any
language, as long as the interpreter itself is written in RPython
and contains a few hints to guide the JIT Compiler Generator.
