+/**
+ * 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/
