## Miscelanous
When using [Iceberg](https://github.com/pharo-vcs/iceberg) to save Smalltalk in this format it is customary to follow the convention of saving Tonel source in a in immediate project sub directory called ```src```. To cause Iceberg to use Tonel format you must additionaly create a file called ```.properties``` in this directory containing the following directive:
```
{
#format : #tonel
}
```
