 ### 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_release`, 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_release`, 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.
