News in Madeleine 0.3:

```
* Automatic commands
* Some classes exported to the default module
* Clock support not loaded by default (require 'madeleine/clock')
* Bug fix: Error handling when replaying logged commands.
* New system through block instead of argument (API change)
* Works in $SAFE = 1

```

Thanks to Stephen Sykes for the automatic commands implementation.
