1. Back end

The bits you need to know how to use to write your own bytecodehacks, or understand how the ones supplied actually do their stuff.

I presuppose quite a detailed knowledge of the Python interpreter. If you don't know what the new or dis modules do, you're not likely to understand what goes on here.

When I talk of ``user'' code in this section I mean code that uses the library to rewrite bytecodes, not end-user code.
