test does testing things
|
||
|
|
```
|
||
|
|
|
||
|
|
By default, the program does nothing:
|
||
|
|
```bash
|
||
|
|
$ 01a_quick_example
|
||
|
|
Debug mode is off
|
||
|
|
```
|
||
|
|
|
||
|
|
But you can mix and match the various features
|
||
|
|
```bash
|
||
|
|
$ 01a_quick_example -dd test
|
||
|
|
Debug mode is on
|
||
|
|
Not printing testing lists...
|
||
|
|
```
