+// Installing an update requires the coordination of multiple processes,
+// `SQRLShipItConnection` is responsible for submitting the launchd jobs
+// required to perform an installation request.
+//
+// The multiprocess approach to waiting for termination and installing is
+// designed to keep uses of AppKit API (i.e. `NSRunningApplication`) out of the
+// installer process - which may be running in the root bootstrap context - and
+// put them in a process running in the user bootstrap context. These processes
+// can then communicate using the file system as a message bus.
+//
+// Frustratingly although LaunchServices is daemon and root safe since 10.5, the
+// LaunchServices API for querying the running applications isn't public
+// (internally `NSRunningApplication` uses this LaunchServices private API,
+// though of course this is subject to change and `NSRunningApplication` could
+// also do other non-root safe things).
+//
+// When a user application running Squirrel wants to install an update, Squirrel
+// submits two launchd jobs, one which will wait for application termination and
+// write an empty file to the given location when the criteria are met, and the
+// other which will wait for that file to appear and then perform the install as
+// before. The "wait for termination" job is always submitted to the user
+// domain, but the installer job is submitted to a domain based on whether the
+// install location is writable by the current user.
+//
+// To perform the relaunch when the install is complete, it is safe to use the
+// LaunchServices API from the installer process, the app will be launched in
+// the user's GUI session.
+//
