"""all.py
Runs all the examples for testing purposes and reports success and failure
to stderr. An example is marked successful if the running thread does not
throw an exception, for threaded examples, such as plotting, one needs to
check the stderr messages as well.
$ ./all.py [-hw]
Options:
-h print this help message and exit
-w Also run examples requiring windowed environment.
Example Usage:
When no examples fail:
$ ./all.py > out
SUCCESSFUL:
- beginner.basic
[...]
NO FAILED EXAMPLES
$
When examples fail:
$ ./all.py -w > out
Traceback (most recent call last):
File "./all.py", line 111, in run_examples
[...]
SUCCESSFUL:
- beginner.basic
[...]
FAILED:
- intermediate.mplot2D
[...]
$
Obviously, we want to achieve the first result.
