What does torchbear actually do?

So after reading all of the README I understand what it is (it's a fancy Lua shell, right?) and what component it uses but what does it actually do? Are there examples besides (also not sure what `speakeasy` is supposed to be):
```
#!/usr/bin/env speakeasy

print("hello from Torchbear")
```

?

Is there a getting started tutorial somewhere? How do I use all those fancy included libraries?

The README seems to contains a lot of answers but very little actually related to this project which is a shame.
