/**
* Sparkle is a software update framework for macOS which uses appcasts for
* release information. Appcasts are RSS-like XML feeds which contain information
* about the most current version at the time. If a new version is available, the
* user is presented the release-notes/changes/fixes and is asked if they want to
* update, and if yes the Sparkle framework downloads a signed update package
* from the server and automatically installs and restarts the software.
* More detailed information is available at the following address:
* https://sparkle-project.org/
*
* WinSparkle is a heavily (to the point of being its almost-port) inspired by the
* Sparkle framework originally by Andy Matuschak that became the de facto standard
* for software updates on macOS.
* More detailed information is available at the following address:
* https://winsparkle.org/
