| As of version 1.1.2, Propane will load and execute the contents of | |
| ~Library/Application Support/Propane/unsupported/caveatPatchor.js | |
| immediately following the execution of its own enhancer.js file. | |
| You can use this mechanism to add your own customizations to Campfire | |
| in Propane. | |
| Below you'll find two customization examples. | |
| 1 - A responder that adds avatars to your chat view | |
| 2 - A responder that displays CloudApp images inline | |
