### Running Pyston
Pyston builds in a few different configurations; right now there is `pyston_dbg`, which is the debug configuration and contains assertions and debug symbols, and "pyston", the release configuration which has no assertions or debug symbols, and has full optimizations. You can build them by saying `make pyston_dbg` or `make pyston`, respectively. If you are interested in seeing how fast Pyston can go, you should try the release configuration, but there is a good chance that it will crash, in which case you can run the debug configuration to see what is happening.

> There are a number of other configurations useful for development: "pyston_debug" contains full LLVM debug information, but can be over 100MB. "pyston_prof" contains gprof-style profiling instrumentation; gprof can't profile JIT'd code, reducing it's usefulness in this case, but the configuration has stuck around since it gets compiled with gcc, and can expose issues with the normal clang-based build.
