All my options for ex62 are in the builder.py script in config/. Here is
how I run an example:

  ./config/builder2.py check src/snes/examples/tutorials/ex62.c --testnum=0

You can run all tests by omitting --testnum, and see the other options
using --help. This requires Python 2.7.

Let me know if anything goes wrong, or you can't get what you want working.

  Thanks,
