As Automator Actions become popular with users, software developers are consistently jumping on the bandwagon. One way developers let users of their apps take advantage of Automator is by shipping Automator Actions with their applications, or to be exact, shipping their applications with Actions embedded in them. These actions will appear in Automator just by the virtue of the application being installed on your Mac.
The way developers can include Automator Actions with their applications in this manner is by placing them inside the application’s bundle. Tiger can smell files placed inside the application bundle if they’re placed inside the folder: Contents/Library/. Actions placed in the Contents/Library/Automator will be shown in Automator. To see the contents of a bundle, control-click the bundle and choose Show Package Contents.
