            /**
  Sample Propane caveatPatchor.js file based on tmm1's avatar hack.

  You'll need at least version 1.1.1 to experiment with this:
  http://propaneapp.com/appcast/Propane.1.1.1.zip
 
  Once I'm sure exposing this hack-injection point doesn't cause problems
  I'll do an official auto-updating version.

  As of version 1.1.1, 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.

  Please don't tinker with enhancer.js - it's the glue that binds Campfire's
  javascript to Propane's UI and features.

  Also: this is totally and utterly unsupported. By all means you can
  ask me questions via Propane's help forums but I can't debug your scripts
  for you. My javascript isn't that good, trust me.

  Finally, if Propane is acting broken in general and you've got hacks in
  caveatPatchor.js, *please* tell me about your hacks up-front when opening
  an issue on the support site.
