6.5 File associations for a Macintosh application

To create an assocation between your LispWorks for Macintosh application and files with a specified type (file extension):

1. Create the appropriate entries for the file type in the CFBundleDocumentTypes array within the Info.plist file of the delivered application.
2. Define a subclass of capi:cocoa-default-application-interface with a message-callback .
3. Implement the :open-file message in the message-callback function.
4. Set the application interface on startup.
