Need automatical testing script

```
Hi,

I'm going to release a new version of pat. But I found some problems. The 
significant problem for me is to run all examples to ensure the correctness of 
pat.

For now, we don't have testing script to run all examples automatically. Is 
there anyone willing to contribute?

Luba.
