you should put this on the wiki, this is a grate example of the power this holds

In a nutshell, PyOSA makes Python a *full* peer to AppleScript. Appscript is an Apple event bridge, allowing Python scripts to send Apple events to applications. That's great when you want to control one process from another, but no help if you need a script that controls and/or is controlled by its host process. For that level of integration/interaction, you need a full OSA language. PyOSA packages the Python interpreter as an OSA language component, allowing Python scripts to be attached to any OSA-aware application. It also fully integrates appscript, allowing PyOSA scripts to send events directly to the host process and vice-versa. Attachability and integrated Apple event support are essential for tasks like Folder Actions and Mail rules, which you just can't do with appscript alone. For example, you could create a Mail rule that runs an 'AppleScript' action whenever new messages are received. That rule would load a PyOSA script and call its 'perform_mail_action_with_messages' function, passing it a list of message references. The script could then go through those messages, getting and setting their properties, moving them to other mailboxes, and so on. Cool stuff, in other words, and even this is a relatively trivial example of OSA's full potential. Unfortunately, for various historical reasons, OSA has never seen widespread adoption beyond the AppleScript language and a relatively small number of applications. But hopefully a new generation of OSA language components will begin to change this situation for the better.
