// Finding the new version number from the RSS feed is a little bit hacky. There are two ways:
// 1. A "sparkle:version" attribute on the enclosure tag, an extension from the RSS spec.
// 2. If there isn't a version attribute, Sparkle will parse the path in the enclosure, expecting
// that it will look like this: http://something.com/YourApp_0.5.zip. It'll read whatever's between the last
// underscore and the last period as the version number. So name your packages like this: APPNAME_VERSION.extension.
// The big caveat with this is that you can't have underscores in your version strings, as that'll confuse Sparkle.
// Feel free to change the separator string to a hyphen or something more suited to your needs if you like.
